    How do you know what a pancaking building looks like?

    As it's never happened before, there really is nothing to compare it to...
    Before 9/11, I didn't know what it looked like. If, however, I had been asked to visualise the effect of a skyscraper collapsing floor-on-floor in a "pancaking" fashion, I would have visualised something pretty much exactly along the lines of what was portrayed in that video clip.

    I don't know what parallel universe you inhabit, but it's obviously one where 18 floors of a skyscraper have no mass.

    I mean, seriously. Work with me here. What part of "a skyscraper has no mass" makes any sense to you?

    Despite the massive cloud of pulverized concrete, you can still see large objects being launched out away from the building. How were all these objects ejected away from the building, before gravity had a chance to take effect?
    First, I'd really like you to take at least one frame of that video and highlight for me exactly what you're talking about. Second, a friggin skyscraper collapsed - how exactly are you surprised that some debris may have been ejected sideways in the process?

    How does the pancake theory account for the banana peel effect seen?
    I'm not sure what you mean by the banana peel effect, but I'm going to assume you're talking about the splayed aluminium beams toward the bottom of the building. Again, how hard is it to comprehend that if the inside of a building is collapsing, the outside might get bulged somewhat by the internal forces?

    I mean, seriously: does it take a strong conscious effort to avoid understanding intuitively the incredible destructive forces involved when a huge building falls down?
    tunaman wrote:
    What makes you think they are aluminium cladding?
    They look like the metalwork that made up the outside of the building. The spacing looks about right. I've seen the towers in the flesh (as it were), prior to 2001.

    What makes you think they are massive steel beams?
    tunaman wrote:
    I never said they were...
    I guess I misunderstood you. So, your entire objection is to the idea that a collapsing building could possibly have any of its components fall anywhere other than perfectly within its own footprint.

    I don't know how to counter that. I simply can't relate to a failure to intuitively comprehend what happens when a 110-storey building collapses in a catastrophic fashion.
    tunaman wrote:
    That is far from a given, as they came down at very near free-fall speed, which only happens when buildings are demolished.
    You keep saying things like this. You've yet to demonstrate convincingly that (a) the buildings fall faster than can be explained by gravity, or (b) they would fall any faster with explosive charges than if (say) the top of the building collapsed in on the bottom part, causing catastrophic structural failure.
    tunaman wrote:
    What caused the debris to just fly out hundreds of feet in the air?
    Thought experiment for you: imagine you can take an 18-storey building, and drop it onto a 92-storey building. Do you suppose that, just maybe, a few bits might fly out to the sides under the impact?

    I mean, seriously: you seem to be focusing on the awsome destructive power of explosives. Exactly how much TNT do you think it would take to even approach the energy involved in the collapse of a 110-storey building?
    tunaman wrote:
    Here is the aerial view again...

    http://www.solcomhouse.com/Worldtowers.jpg

    Notice that building (green pyramid) is not a neighbouring building, and some massive explosive force was responsible for those steel beams becoming embedded in that building. Gravity is not an explosive force in any way, so how could gravity alone possibly be responsible for what happened?
    Gravity may not be an explosive force, but a 110-storey building collapsing most certainly is.

    Here is the full lecture from a clip which was posted earlier.

    Guys, what you cant say about building seven that day, is that it was brought down by fire. Especially in freefall speed in 4.5 seconds. Fire can do that now??

    A demolition would take more time to plan, as Larry Silverstein failed to mention when he was quoted saying he made the decision to "pull it". One of you guys, either OscarBravo or Bonkey, must see something wrong with the way 7 came down. Demolition style, with no indication of charges being set beforehand!!

    It defies logic. I know im probably just churning out what has been said earlier, but this just doesn't add up.

    I'm not basing my objection on our freedom to express opinions. I'm basing my objection on the rules of this forum which explicitly limit that right.

    You could argue that I was disingenuous and misleading in not pointing out why the "freedom to express opinions" argument was inherently flawed, and I'd accept that. I was prepared to be caught out on that one. Its why I never said that NoelRock was right...I said that the reason offered for him being wrong led to a double standard. There is a distinction which you've apparently missed.

    Note that my objection to your insults are not based on the same reason. Mine are based on the fact that the charter obliges you to be respectful.

    Thus, there is no double standard on my part.

    Ou could still argue that its unacceptable for someone to not fully disclose the weaknesses in their own arguments....which is the tactic I employed when responding to CB.

    If you want to say I shouldn't do this, go right ahead. I can take it as acceptance that all of your own arguments which don't give the full pertinent details are also unacceptable in your own eyes.

    Well, given that it took longer than 4.5 seconds, which is faster than freefall for a vuilding that size, I can agree wholeheartedly that fire did not cause the building to collapse in freefall in 4.5 seconds.
    One of you guys, either OscarBravo or Bonkey, must see something wrong with the way 7 came down

    I see a lot wrong with the claims people make about how it came down, how long it took, what the causes were, etc.

    For example, the main theory still being worked on is that massive damage to the face of the building closest to the towers (caused during the collapse fo the nearer tower) was more-or-less un-noticed.

    This is disregarded by people showing pictures from the other side of the building using some so-called logic which says that if two/three sides weer relatively/totally undamamged, then the roof and other side must also have been in perfect condition, even though they were the locations most likely to be seriously damaged!
    It defies logic. I know im probably just churning out what has been said earlier, but this just doesn't add up.

    I don't agree that it defies logic, unless the "it" in question is one of the misrepresentations of what the official version is.

    No official version has faster-than-freefall or freefall speeds.

    The FEMA version does have the fire theory, but it also has a precursor to that where FEMA say they don't accept it themselves, and that further investigation is therefore needed. People seem to overlook that FEMA were required to give a "best guess" in the absence of certainty, that they made sure to point out how weak a guess it was, and that they subsequently comissioned a very expensive, very detailed, still-ongoing investigation into what did happen. They also seem to overlook that the interim report on this investigation has a totally different and far more credible theory than the FEMA one, and that this should be taken as the current theory-to-question rather than the FEMA guess.

    As for what it looks like...I couldn't care less. There's pictures of smoke from the towers where one can see what looks like devils faces in the smoke. Do I believe devils were animating the smoke because thats what it looks like? No, I don't. Am I wrong for doing this...after all, its not impossible that Forces of Darkness roam the world and inflict such disasters on men. Surely if I keep an open mind I should accept the possibility that it was really demons behind it all, right? Or can we agree that "looks like" is not a good basis for conclusion?

    - Longest sentance ...ever.

    That clears that up. Speaking of best guesses and such, wouldn't the Pancake Theory be just a theory?? It seems to be closest to reality for some folks.

    Wouldn't an explanation like a failure in architecture or spastic core beams be a more feasible theory?? Or fire vents that were supposed to be open were somehow shut that day and retained all of the heat??

    Ok... maybe i phrased the "what it looks like" wrong. And i subsequently started somebody on a rant about faces in smoke. That was on the front page in the sun a couple of days after 911 actually.

    Ahh sure it is the conspiricies (typo?) forum after all... when in Rome!!

    Well, i think you know what i meant, and i think we might both conclude that fire wasn't the main cause in building 7!! I dont like making conclusions for someone else, but it sure seems that you might think that way from the previous post and the "appearance's" and video footage from that day.

    Maybe it (7) was somehow tied in to the foundations of WTC 1 + 2, but i seriously doubt that. Bonkey, how can anything be scientifically clarified and investigated, if everything was removed and fecked into boats bound for china, ignoring the normal procedure of sifting through evidence? I think most people have based their opinions and theorys on "what looks like".

    This thread is pointless, because there never will be evidence to support what i think and what Tunaman thinks happened (maybe two differing trails of thought, but along the same lines!!), because it was all taken away and sold for scrap.

    This video might change your mind. You dont have to listen to all of the shíte that they talk about, just fast forward to 3 mins 40 seconds. And use a stopwatch or something...

    Specially with the full stop in the middle that you overlooked ;)
    That clears that up. Speaking of best guesses and such, wouldn't the Pancake Theory be just a theory?? It seems to be closest to reality for some folks.

    "Just a theory" is a comment that will make pretty-much anyone with a background in science wince when they hear it.

    A scientific theory is just-about the Holy Grail of standards in science. It means that something has been shown to be true to the extent that we can assume it to hold true in general within the framework that the theory is referencing. In the scientific sense, a theory is as close to reality as you get.

    If the term is being used in this manner to refer to the pancake theory, then the only way in which it can be inapplicable is to scientifically find a single refutation. If a theory predicts something, then one single counterexample where it says this something will happen but is wrong disproves the theory. However, appealing to the senses (common or otherwise) that you don't believe it is not a counter-example.

    If, of course, the pancake theory is not a theory in the scientific sense, then its still inaccurate to argue that "just a theory" applies. After all, those demon head pictures are just an idea as well. As is the idea that it was all done by space-aliens who actually used an invisible death-ray from their moon-base with an illusion of an airplane (which they vaporised with a second blast somewhere else and so on and so forth).

    "Just a theory" isn't an arugment whichever way you look at it. Not all ideas are equal, and there is no "just" about scientific theories.
    Wouldn't an explanation like a failure in architecture or spastic core beams be a more feasible theory??
    Nope. It would require more initial conditions to be true, and it would also require that one show those conditions being true would not cause a collapse under normal load conditions.
    Or fire vents that were supposed to be open were somehow shut that day and retained all of the heat??
    Supposition has no place in theory. Either we can show that they must have been in this state, or we discard the possibility.

    Think of it like this....if a model shows that with no hidden factors, the impact and resultant fire should have led the building to collapse in the manner observed, then what reason do we have to introduce additional factors to make the building collapse?

    Furthermore, if we wish to introduce additional factors, then we should be able to show that they result in an equal or better fit at the very least. Again, this is meant in the scientific sense. Its nto an appeal to guesswork, gut feeling, eyewitness accoutns or anythng else. You don't trump a mathematical model using proven modelling techniques by appealing to gut feeling and what you thnik it should have looked liek. You trump it with a better model.
    Well, i think you know what i meant, and i think we might both conclude that fire wasn't the main cause in building 7!!
    I think everyone has accepted that.

    The problem is that those who wish to pour scorn on the official version want to trump up the original "best guess which is almost certainly wrong" and make it out to be "best guess which we'll stand over, believe to be true, and no-one's said anything different since". Seriously - the only people who you'll see make the claim that this is a serious theory any more are those trying to ridicule it....and/or perhaps those who haven't followed the story since the FEMA report came out.
    Bonkey, how can anything be scientifically clarified and investigated, if everything was removed and fecked into boats bound for china, ignoring the normal procedure of sifting through evidence? I think most people have based their opinions and theorys on "what looks like".

    Because everything wasn't removed and fecked into boats bound for China.

    NIST had metallurgical samples made available to them, and have never once complained about the insufficiency of this information. Furthermore, a lot of their work involves serious collation of the photographic and video evidence. Note that this doesn't mean cherry-picking the view of the building that suits their theory....this means searchnig all footage to get as complete a picture as possible.

    They have only had partial success - they admit that there are still difficulties modelling the collapse, but that they're pretty certain that at least 1/3 of the building was destroyed by falling debris despite three of the faces being almost-totally intact. Their working model, from what I recall, had the building more-or-less collapse while leaving these three faces intact, and those are what we then see collapse straight down.
    This thread is pointless, because there never will be evidence to support what i think and what Tunaman thinks happened (maybe two differing trails of thought, but along the same lines!!), because it was all taken away and sold for scrap.
    Thats not true. Jones' work alleging the use of thermit has made use of photographic, eye-witness and physical evidence - exactly the same stuff that NIST has done.

    While I disagree with his findings and have pointed out what I believe to be flaws in his research, its clear that the allegations of there being no physical evidence and that a proper investigation cannot be carried out do not hold up.

    Its also noteworthy that what you've just posted is an admission that you have a conclusion without the evidence to support it. On what grounds can you therefore criticise any other conclusion?

    Woop, didn't notice that, damn my lazy eyes, not noticing, caring or paying attention to things.... Maybe all us non official story liking people have some new form of eye disease, affecting the part of the brain that takes in images and blurs them into our own sick twisted beliefs!!

    What to call this new illness?

    You might want to get in touch with someone so change this terminology. After all, it is an official government backed "explanation". maybe change it to a nicer one, for example, Pancake law of collapse??? I modelled this on the terminology "Newtons law".

    After all, it is an official government backed "explanation". And no other fallback theory has been introduced. So thats what happened then. And if sears tower fell tomorrow due to fire damage, the forth high rise steel strutted building in history to do so. Maybe we could pass it off as that too!

    Surely someone will agree, like teh cliché dissenting republicans! - tv episode quote, me trying to be funny, not to be mistaken for trolling/insult.

    I do that, of course without adding numbers or finding out wind resistance or any of that crap!! Metallurgical samples, are these things teh scrapings they got off the road those days? Of course NIST didnt complain, i believe they worked backwards from the conclusion in the first place.

    They probably have difficulty modelling the collapse because they cant really make out the cause of the problem. I can imagine them sticking burning matches into this "model" and scratching their chins. Hmmm...

    What is there to search though though? Other than small "samples"? In physical evidence terms. You must find it odd that most of it was cleaned when the dust settled?

    Is this NIST models partial success the valid evidence you hold to support your arguement/conclusion? Or is it all the video footage? Video footage in NIST and even Jone's case, could be classified as "what looks like".

    I know im probably wrong here, but we seem to be in the same boat, quite like all that debris!!.

    Pancake theory slated on most of these results. It seems that this theory isn't really as sound as some would think

    At first glance I agree, I think to most people it just looked like a building collapsing. However that slow motion clip I presented, does not look anything like a building merely collapsing.
    I don't know what parallel universe you inhabit, but it's obviously one where 18 floors of a skyscraper have no mass.

    18 INTACT floors of a skyscraper have mass alright, but you seem to be ignoring the fact that the floors were being pulverized into a fine dust.
    I mean, seriously. Work with me here. What part of "a skyscraper has no mass" makes any sense to you?

    The part that has exploded...

    http://img57.exs.cx/img57/463/0f-WTC1Implosionfrom.jpg

    There is no mass above the remaining intact floors, so the pancake theory couldn't possibly have happened...
    First, I'd really like you to take at least one frame of that video and highlight for me exactly what you're talking about. Second, a friggin skyscraper collapsed - how exactly are you surprised that some debris may have been ejected sideways in the process?

    Here is the clip again...

    http://rei-rom.com/images/wtc1.gif

    I am talking about large parts of the building being rapidly ejected, which can be seen during the whole clip. Notice that the clip starts with the very top of the building, which according to the pancake theory was the part of the building responsible for destroying the lower floors.

    How is that possible if that section exploded?
    I'm not sure what you mean by the banana peel effect, but I'm going to assume you're talking about the splayed aluminium beams toward the bottom of the building.

    I am talking about this effect seen during the collapse...

    http://video.google.co.uk/videoplay?docid=857154317067257405&q=wtc+collapse
    They look like the metalwork that made up the outside of the building.The spacing looks about right.

    I agree.

    The exterior columns were not made of large pieces of steel?
    I guess I misunderstood you. So, your entire objection is to the idea that a collapsing building could possibly have any of its components fall anywhere other than perfectly within its own footprint.

    I don't know how to counter that. I simply can't relate to a failure to intuitively comprehend what happens when a 110-storey building collapses in a catastrophic fashion.

    My entire objection is the pancake theory fails miserably to explain what happened to the twin towers, which according to the US government fell at free-fall speed. The only rational and logical explanation is explosives.
    You keep saying things like this. You've yet to demonstrate convincingly that (a) the buildings fall faster than can be explained by gravity,or (b) they would fall any faster with explosive charges than if (say) the top of the building collapsed in on the bottom part, causing catastrophic structural failure.

    If the pancake theory is what happened, then why was there absolutely no resistence of any kind from the lower floors?
    Thought experiment for you: imagine you can take an 18-storey building, and drop it onto a 92-storey building. Do you suppose that, just maybe, a few bits might fly out to the sides under the impact?

    Yeah, but would you expect the 18 storey building to completely disintegrate?

    Then still amazingly manage to completely destroy the 92 storey building?
    I mean, seriously: you seem to be focusing on the awsome destructive power of explosives. Exactly how much TNT do you think it would take to even approach the energy involved in the collapse of a 110-storey building?

    No idea, as I have never seen a 110 storey building collapse...

    The reality is that there is clearly a double standard on your part.

    From a post you made from a few days ago in this thread, which was directed at me...
    It also scares me, frankly, that you need a link to the retraction. I'm amazed that you aren't familiar with is, considering that you've been rubbishing for so long.

    I just ignored this obvious insult at the time, but seeing as you are playing the role of the victim, I thought I would bring it to people's attention. ;)
    If you want to say I shouldn't do this, go right ahead. I can take it as acceptance that all of your own arguments which don't give the full pertinent details are also unacceptable in your own eyes.

    Everybody has heard the seriously flawed official version of events for nearly the last 5 years now...

    I think you will find I have absolutely no problem presenting as much video and photographic evidence as I can, so it's a bit much saying I don't give the full details.

    You might want to get in touch with someone so change this terminology.
    Well, to be honest, I don't know whether or not it is meant in the scientific sense or not.

    Either which way, the point I was making is that "just a theory" is pretty meaningless as a critique regardless of whether or not it is meant in the scientific or non-scientific meaning.
    Of course NIST didnt complain, i believe they worked backwards from the conclusion in the first place.
    And this is where my fundamental problem arises. These guys know what they are doing and are generally held in high regard (911 alternate-theory believers excepted).

    You can believe they approached it back-to-front if you wish, but unless you can provide compelling evidence - or indeed any evidence at all - that this is what actually happened, then to be honest what you're ultimately doing is saying that speculation on your part is enough to discredit their findings. Indeed, it would be indicative of you doing what you are criticising them for - you're discarding their work because you have concluded its poorly done, rather than analysing their work and drawing an objective conclusion.

    Tunaman has oft-stated his similar beliefs, as well as assertions that they never considered alternatives, and all I've done is asked for someone to prove such assertions, or indeed provide evidence to back it up. Bear in mind that NIST couldn't just come out and say "explosives/thermal charges were used". They'd have to model where they were used, how they were used, show how they could have been detonated (neither radio nor wire-based signalling would be possible), show how the impact of the planes didn't disturb /predetonate charges in WTCs 1 and 2, explain why no expected trace elements were found in the metallurgical samples they did have, and so on and so forth. Anything less would be a theory even more full of holes than the one thats being dismissed by its critics for incompleteness.

    Incidentally, have you noticed that not one of said critics has held up any other disaster analysis (e.g. from a normal plane-crash) to show just how much more complete an analysis following large-scale unanticipated destruction should be? Has it never occurred to anyone to do this? Are they too lazy to do it? Or have they checked and found there is nothing exceptional about the NIST report? Thoroughness seems to be utterly lacking on the part of those criticising NIST for a lack of thoroughness.
    I can imagine them sticking burning matches into this "model" and scratching their chins. Hmmm...
    :) And smoking their pipes over tea, what? No, NIST are not pre-WW2 english gentlemen. You can mock them all you like, but seriously...these guys are seriously good at what they do.
    You must find it odd that most of it was cleaned when the dust settled?
    Yes, I do. I've never claimed that I'm perfectly happy with everything that went on, and this is one aspect I disapprove of, but not for the reasons that MIHOPers and the like keep coming up with.

    BEfore it was hijacked and mis-represented to be support of the conspiracy theory, FDNY issued a complaint about this very issue, on the grounds that they believed there was a hell of a lot to learn about high-rise fires in general from these events. They do not accept that the standard (oft-repeated by alternatists) line that fire cannot collapse buildings and felt that the removal of the waste prevented the possibility of learning more to improve fire-fighting and life-saving techniques, as well as to learn lessons for future construction.

    There is unquestionably the possibility of a conspiracy of this nature being present - that political games were being played to ensure that the standard line of "steel buildings don't just burn down" is kept, because a change in that belief would have immense commercial ramifications. Of course, such a conspiracy isn't sezy enough by far to grab people's interest, because it would be more classified as "business/politics as usual" than anything sinister.
    Video footage in NIST and even Jone's case, could be classified as "what looks like".
    Yes, it could. Have you read the reports? Is this what you think they're doing? If so, can you point to where they are doing it? If you haven't read the reports, then how can you critiquem criticise or dismiss them?
    I know im probably wrong here, but
    There is no but. If you know you're probably wrong, then surely you should be looking to reevaluate your opinions....not just hold out in the vain hope that someone else will show you to be right.
    Pancake theory slated on most of these results. It seems that this theory isn't really as sound as some would think
    There's no shortage of people who criticse the pancake theory, What there is, is a shortage of qualified people to criticise it. All of the critics are effectively laypeople in the relevant fields and not one of them has "disproven" the theory. They've applied poorly-formulated tests (at best) to it and/or thought-experiments and decided that they don't accept the validity of the conclusion.

    Its a bit like me saying that I don't accept gravitational theory, cause I've done some thought experiments and played with some lego and a stopwatch and decided that this proves its all a load of hogwash so we can discard what all of those scientists and their fancy schamncy equipment have said cause clearly they're just after cushy grant money to buy shiny toys.

    Cause its friday afternoon, I thought I'd add the following....

    I take it all back.

    I'm not completely in agreement that NIST didn't consider any alternative theories.

    The proof can even be found in the NIST report!!!

    Download NIST NCSTAR 1-6: Structural Fire Response and Probable Collapse Sequence of the World Trade Center Towers .

    No...wait...what am I saying...

    Open the copy of this you no doubt already have, because surely you must have read it if you're debunking/supporting it and its an invaluable source to keep close at hand.

    Anyway...where was I...oh yes....

    Open said document in your PDF-reader of choice and go to the end of section 9.3. On my copy, thats on page 402. Final paragraph before section 9.4.

    See what they say!

    The proof is there!

    I really don't see how anybody can suggest, that after closer inspection, that it doesn't at least look like a demolition job...

    No two building collapses are ever going to look the exact same, which was proven by the differences in the so called collapse of the twin towers.
    Now you're displaying a complete ignorance of basic physics. How, exactly, does pulverising something to fine dust reduce its mass?

    In this case, the object was 18 floors of skyscraper, so when it disintegrated into thousands of smaller and airborne pieces, the overall mass of the object was greatly reduced.

    It's not possible for the upper 18 floors to act as a massive hammer to crush the building below if it is no longer a rigid object.

    All that remains, above the point of contact with the solid structure below, is nothing but AIR above. So there was no cumulative weight loading, in fact just the opposite - a cummulative weight unloading.

    Free-fall speed was calculated at 9.2 seconds. The US government claim the south tower collapsed in 10 seconds, so as you and others take them at their word, you must surely agree on something this important?
    Look at this video, about 35-40 seconds in. You can clearly see the intact top section of the building toppling sideways as it falls.

    I don't really know what your point is, but I suggest you look at what happened next...

    http://plaguepuppy.net/public_html/collapse%20update/wtc-2.jpg

    The top section of the building disintegrates, before it had a chance to destroy the lower floors...
    That's not amazing at all. Unless you assume that 18 storeys' worth of building suddenly stopped having mass.

    How was the mass able to overcome resistance so methodically? If the floors were being destroyed at a rate of 10 floors a second, then the area mass of falling building would have depleted itself of mass in less than 2 seconds.
    As a matter of interest - if the debris from the top 18 floors didn't have any mass - why did it fall to the ground?

    Since the majority of mass was being ejected out what was left to cause the collapse to continue?
    I've seen two, and so have you.

    I thought so too, until I actually looked at all the evidence...

    The proof can even be found in the NIST report!!!

    I'm not about to download or trawl through that garbage to find what you think is relevant, so why don't you post the enlightening section in the thread?

    Unless of course you mean this...

    NIST found no corroborating evidence for alternative hypotheses suggesting that the WTC towers were brought down by controlled demolition using explosives planted prior to September 11, 2001.

    I bet they looked really hard...

    NIST also did not find any evidence that missiles were fired at or hit the towers.

    Why would they even mention missiles?

    Instead, photos and videos from several angles clearly showed that the collapse initiated at the fire and impact floors and the collapse progressed from the initiating floors downward, until the dust clouds obscured the view.

    What did you say about people who use clearly in their arguement? :)

    I am a man of speculation, and skepticism, same as yourself (the skeptic part). My speculation is not going to discredit anyones findings. Definatly not the National Institute of Standards and Technology. This isn't exactly the countrys foremost debate, suggested change and idea source!

    You have your views and i have mine, simple as that, im not doing this to get at you. Think of a tv show, a comedy if you will, because thats what i see the official story and pancake theory as. You like it, i dont.

    Most materials of the NIST report were based on external images of the buildings, i got the feeling that they thought the external columns were what was keeping the building up!

    http://911research.wtc7.net/wtc/evidence/blueprints.html
    The blueprints to the Twin Towers and Building 7 remain off-limits to the public three years after the attack, despite the fact that the buildings were built with public money and that the engineering drawings of public buildings are supposed to be public information
    Did NIST have access to these blueprints? If the model was drawn precisely to these blueprints, would NIST not be liable for more or less releasing these blueprints in this vastly diagramed report of theirs?

    And if they took all of this data into account, would they not recreate an accurate computer model and explanation of the collapse? No... not very accurate models, ahh dammit.

    I see fishy things about. Like the put options on American Airlines on Sept 10.

    http://www.hereinreality.com/insidertrading.html
    [FONT=Arial, Helvetica, sans-serif] Between September 6 and 7, the Chicago Board Options Exchange saw purchases of 4,744 put options on United Airlines, but only 396 call options… Assuming that 4,000 of the options were bought by people with advance knowledge of the imminent attacks, these “insiders” would have profited by almost $5 million.

    [/FONT][FONT=Arial, Helvetica, sans-serif] On September 10, 4,516 put options on American Airlines were bought on the Chicago exchange, compared to only 748 calls. Again, there was no news at that point to justify this imbalance;… Again, assuming that 4,000 of these options trades represent “insiders,” they would represent a gain of about $4 million.[/FONT]
    $9 million, would you risk complete and utter foreknowledge disclosure for this amount if you had picked the money up? No? Neither would they... evidently...

    And what about Silversteins lucky payouts, after being leaseholder for three months. Didn't get the multiple insurance claims you wanted from two seperate attacks huh Larry? Ahh well, you got a few Billion anyways.

    [FONT=Callisto MT,Georgia,Book Antiqua,Palatino,Times New Roman,Serif]
    It is interesting, in considering this idea, to look at the actual times that the Twin Towers stood after the impacts. As noted in Section 2, the North Tower was hit first, at 8:45 a.m., in a direct hit and most of the plane's fuel entered the building, causing a huge fire. Then at 9:03 a.m. the South Tower was hit, but the plane hit the tower toward a corner and at a shallow angle, and comparatively little of the jet fuel entered the building, most burning up outside.

    In both cases the fires within the buildings died down after awhile, giving off only black, sooty smoke. If the Twin Towers were deliberately demolished, and the intention was to blame the collapse on the fires (as the official story has it) then the latest time at which the towers could be collapsed would be just as the fires were dying down.

    Since the fire in the South Tower resulted from the combustion of less fuel than the fire in the North Tower, the fire in the South Tower began to go out earlier than the fire in the North Tower. Those controlling the demolition thus had to collapse the South Tower before they collapsed the North Tower. And in fact the South Tower collapsed at 9:59 a.m., 56 minutes after impact, whereas the North Tower collapsed at 10:29 a.m., 1 hour and 44 minutes after impact.

    But again, i am spouting out what im in no doubt has been said earlier.

    It is important to note that initiating the thermite reaction requires temperatures well above those achieved by burning jet fuel or office materials -- which is an advantage of using thermite charges over conventional monomolecular explosives such as TNT, RDX and PETN. Below is a photograph of an experiment performed by the author and colleagues at BYU in which a sample of thermite was heated to orange-hot temperature (about 1700 oF).

    We demonstrated that the thermite reaction would not ignite at this high temperature. Later, the thermite reaction was triggered by burning a magnesium strip in contact with the thermite. An electrical superthermite "match" could have been used and remotely triggered via radio signal.

    No, it didn't. Looking at carefully selected stills, where the progress of the collapse is obscured by dust clouds, you could convince yourself of that - if you really wanted to. If, however, you actually wanted to understand what really happened, you'd look at several different stills and video clips taken from different angles, and you'd clearly see the intact top of the building collapsing in on the lower part, rotating as it did so.

    I see fishy things about. Like the put options on American Airlines on Sept 10.
    Just as I thought we could have a discussion on a single topic for a while...

    Whether or not these options are fishy has nothing to do with whether or not the buildings were collapsed by explosive or thermal charges in asddition to planes crashing into them.


    Regardless of who was behind it, whether or not the buildings collapsed, were blown up, shot down, melted, or whatever you like, all that would ened to be known for insider trading was that the airline industry was about to get shafted, and these airlines in particular. If the WTC stayed standing, that would still be true. If the planes were all shot down and no building attacked, that would still be true. If the buildings were blown up, blown down, melted, exploded, imploded or anything else...that would still be true.

    So the fishiness of those transactions (if indeed they were fishy) neither adds to nor detracts from any of the explanations of why teh buildings fell. All it tells us is that someone might have had foreknowledge.

    http://www.911myths.com/html/put_options.html for more info on whether or not it was fishy.
    And what about Silversteins lucky payouts, after being leaseholder for three months. Didn't get the multiple insurance claims you wanted from two seperate attacks huh Larry? Ahh well, you got a few Billion anyways.
    BTW Larry, you also get lumped with the obligation to rebuild the buildings - given that this is what the insurance was for - as well as having to maintain the rent-payments for the period of the lease despite there being no buildings there any more. Tough luck there pal - huge liabilities and no income for the next...ohh...5 years and counting. But look on the bright side...if they never get rebuilt, you only have just over 90 years more rent to pay on a no-income hole in the ground.

    Silverstein has not been made rich by this.

    But again, i am spouting out what im in no doubt has been said earlier.
    Indeed.

    Its also no coincidence that I point to 911myths.com whenever possible. It answers most of the frequently re-occurring questions, at least to the point where further discussion becomes interesting.
    What is the exact quantity of these samples? Are they microscopic? Give me (a lamen :P) an idea.
    How can you dispute the findings if you don't already know this information? ;)

    But no, they weren't microscopic. They were sufficient to meet NISTs needs, and they were also sufficient for Prof Jones to use in his paper postulating the use of thermite/thermate. You can even see a photo of one piece of the stuff in his paper, which you'll find here.
    As i have said earlier, no thorough investigation can be achieved without evidence.
    You've also just asked a question indicating that you don't actually know what the evidence was.

    This comes after another question as to whether or not blueprints of teh building in question were made available to these people.

    SO I'd suggest that you're right. No inbvestigation can be achieved without evidence, and so far you're showing that you don't have the evidence to call NISTs findings into question, nor do you know whether or not they have the evidence to have made their claims in the first place.

    To be honest, the burden on anyone questioning NISTs findings is not to pose questions, but rather to pose and answer them and thus show that NIST have failed somehow. Show that their physical evidence was insignificant, rather than wonder if it might have been.

    The burden of proof (BoP) is on the person making a claim. NIST have done their research and their collected reports are not just a summary of their findings, but a detailed documentation of how they reached them. They have met their requirements regarding BoP unless it can be shown otherwise. Anyone wishing to call their results into doubt need to show that the methods/results are wrong, not simply suggest that they might be.

    One can refuse to believe them all one like - belief is a personal perogative - but don't expect many to put your faith over their science.
    But I'm not suggesting that the plane would have ignited thermite, had thermite been present.

    I'm suggesting that had charges been present, then the charge and the ignotion-mechanism and whatever means of receiving a signal would all be present. Fine - lets assume thermite was used. What should have ignited the thermite? Can we assert that this ignition mechanism was also plane/fire proof? How did this ignition mechanism receive a signal? Would that in turn not also have to be fire-proof?

    So for the floors above the impact point to have broken off and to have come crashing down on teh rest of the building, and for it to have been caused by cutting charges....some of those charges would have had to have been on the floors where the fire went off. The charge, the initiator/detonator, and the signal-receiver would all have to be fire-proof and impact proof (a plane went smashing through there).

    Simply arguing that thermite wouldn't catch fire isn't enough.
    Why not? I do believe ive missed something, ill read back a bit, sorry!
    [/quote]
    Hmmm...maybe it hasn't...

    OK...lets take wire-based first. How do you prevent the wires from burning, given that a fire was raging throughout a number of floors, which couldn't have been predicted with accuracy in advance. How did the wiring get done with no-one noticing (even if we assume the explosive/thermal charges could be smuggled in and placed). Where was it detonated from? Also consider that the lift-shafts - the obvious place to put such wiring - were also the prime path for the fire to spread downwards.

    As for radio-based, which obviously seems more intuitive...its unfortunately the same problem. FDNY reported problems and difficulties with maintaining communications. Its a fairly well-established fact regarding large skyspcrapers - that its difficult-to-impossible to get a consistent signal. Now, consider just how preceise a demolition is - hundreds/thousands of charges going off in a carefully timed sequence. You simply can't do that with unreliable communications, which radio would have been.

    Now, consider that NISts study shows collapse initatied at the crash-level (and that the BoP is subsequently on anyone challenging their findings to show that those findings are wrong). So the key charges must have been thse shock-proof, fire-proof, able-to-receive-a-signal ones...despite the fact that they couldn't have been determined in advance. So now, not only do we need charges to resist the impact and fire, we also need a detonation sequence that cannot be calculated in advance.

    And again...BoP requires that anyone favouring an demolition scenario show how it was done. All Im doing is pointing what that "how" needs to cover.
    was just illustrating the point that no valid, even scientific conclusion of a collapse can be made from just photographs and video footage of exterior columns. i.e. "what looks like"

    This is not what NIST did, so from a perspective of challenging them its not terribly relevant.

    On the other hand, it does mean that you've accepted that no counter-theory can be considered scientific or valid while it limits itself to these methods....so thats about 99% of CT-believers and CT-arguments done away with.

    Incidentally, while I agree its not sufficient to do everything, there's quite a lot that can be scientifically determined from exterior-based data. Thats because when you look in fine enough detail (e.g. frame-by-frame in video, measuring angles, speeds, etc. accurately is possible and one is no longer dealing with "looks like".

    Here's a simple example. People have posited that the buildings fell at (and sometimes faster than ) freefall speeds. One can identify, however, free-falling debris outside the footprint of the building, falling at a faster rate. As some MIHOPers have been wont to ask - did the laws oh physics stop working that day? Did these clearly-in-freefall objects fall and accelerate faster than freefall ? If not, then the only alternative is that the main body - which can be (and has been) shown to be falling and accelerating at a measureably slower rate - was not falling at freefall rates. This is based on nothing more than visual evidence, but is fully valid from a scientific perspective. So while it might look like freefall, one can scientifically determine that it isn't.....all from visual evidence only.

    Unless of course you mean this...
    <edt>
    Well, presumably you haven't made yourself a liar and looked at what you said you're not going to, so I take it you're simply speculating that this is what I've referred to.

    As usual, its further confirmation of your "standards" of verification, where speculation wins out over cold hard verifiable fact.
    </edit>
    I bet they looked really hard...
    You bet that, do you? Gosh...thats a pretty convincing argument you have there...especially since up till now you've been asserting they didn't even consider other possibilities at all.

    More speculation...
    Why would they even mention missiles?
    Because it was an oft-repeated consiracy claim, perhaps?

    I think you'll find that your beloved Loose Change even mentions it.

    Enlightening to know that you show you are as unfamiliar with the details of the sources you supposedly put weight behind as the ones you disagree with.
    What did you say about people who use clearly in their arguement? :)
    If you were familiar with the NIST report, you'd understand why my criticism doesn't apply in this case. They've already established why it is clear so they're clearly not trying to avoid having to explain this.

    Given that you're unwilling to read their report, though, its unsurprising that you don't know much about what you insist is wrong.

    <edit2>
    It should be noted that while it is simple to criticise NIST for not providing more information about their claims regarding alternate theories, its virtually impossible for them to have done so.

    How can you prove you didn't find something? Realistically, you can't.

    However, what critics of the report overlook is that this should present the single weakest statement in the entire report if explosives were used. All one need find is one single example which could only have come from demolition methods, at which point the credibility entire NIST report falls apart....and all based on that one comment.

    Needless to say, no-one has come close. People have pointed at things that might be clues, but might be something else.

    So NIST make this claim, that tunaman bets is the result of no serious work at all...but all of those thousands of demolition-believers including himself have singularly failed to manage to undermine this claim that they all-so-quickly dismiss. What does that say about their work?

    </edit 2>

    I think blueprints would have also stated if there was a problem in costruction in 1,2 and 7. Which there obviously was, particularly on that day.

    It's falling over to a side! Anyone would think that this part of the building would have tipped over and fell into the street below leaving a considerable amount of the upper floors still partially intact (until it hit the ground of course, covering a few blocks!). Before the rest of the building had a chance to "pancake".

    The odd thing is though, that this part seems to just disintegrate as the rest of the building is falling, how could this happen unless all of the floors above the point of collapse failed simultaneuosly? Did it lean one way first, and then balance out somehow?

    Wow, you love this report. Im sorry that i dont like it bonkey, you'll just have to get over that fact. Im sure it was conducted in good faith. Do i have to give evidence of contrary opinion about every subject to you?

    I'll be more careful voicing my opionions next time.

    Why do i think these horrible, inconcievable things about that day? Because building 7 came down in a matter of seconds in the same manner as buildings 1 and 2. Charges would have taken months to plan, but no, "fire" caused it to collapse... yeah.. sure.

    If you can prove to me that building 7 came down by fire or by any other means than explosive charges, then i'll consider the NIST report being sound! Other than that, you have to (you dont have to, but you might!) consider that 1 and 2 might have been brought down in the same unexplained and unbelievable way. Albiet in a more advanced way than building 7 taken into consideration your wonders about detonation means, which i now wonder about myself.

    You ask how no one noticed explosives being placed in 1 and 2? Why did they not notice 7? If it did indeed come down by detonation.... *cough*
    it did, of course it did!

    The wind didn't knock it down, unless this new winds force was focused on it from above by those aliens you were talking about earlier. Well, i interviewed the both of them, here is an excerpt:

    Me: "Wind, did you knock building 7 with some unimaginable force from above?"

    Teh Wind:"No i Didn't, the aliens did it, i swear... tttt talk to them!"


    Me:"Aliens, you were playing along with the wind weren't you? Look at me, you did it!!!

    Aliens: "Stop hitting me please, i swear i didn't do it!!"

    Below quote link (interesting, worth a read)
    [FONT=arial,helvetica] Now this whole controversy between the "melted steel" scenario and the detonation scenario is one that could be very easily resolved. All we have to do is dig up the steel beams and examine each and everyone of them. If an explosive device caused the steel to fail, there will be tell-tale indications for the engineers to see. But if it was intense heat that caused the steel to "melt" or "buckle", there will be tell-tale signs of that as well. All we have to do to put an end to this controversy is to closely examine the steel. Right? [/FONT]

    Lets just consider that it might "not look like freefall". Then why the hell did the speed of collapse not start off slow, and finish fast (lol, a bit like meself!)? I do believe it started off pretty fast, in both cases. In fact, each building came down in around 10 seconds.

    Look for yourself. This video asks about building 7 as well. I dont see a slow start for the WTC's. As the mass from underneath got pulverised from the top, it should have contributed to the speed on the way down. It should have took a few seconds more to get started at least. Every floor just seems to fail simultaneously. With feck all resistance.

    The cores and floors below that were not affected by fire should have given some resistance even before the mass was substantial enough to crush the building.

    And i do retract my 4.5 second 7 collapse. The link i gave seems to suggest it was 6.4 seconds. Im sorry for this earlier remark.

    It's falling over to a side! Anyone would think that this part of the building would have tipped over and fell into the street below leaving a considerable amount of the upper floors still partially intact (until it hit the ground of course, covering a few blocks!). Before the rest of the building had a chance to "pancake".
    This is a misconception based on a misunderstanding of the physics involved. People see the top part of the building "falling over", and wonder why it didn't land "beside" the wreckage of the building entire.

    Thought experiment once more (and I'm directing this at those who, unlike tunaman, seem to have some interest in the actual physics of the event). Whether caused by jet-fuel and office-furniture fire, or by any other means, imagine that a catastrophic structural failure has occurred as indicated in the photograph you posted. The top half of a huge 110-storey building collapses assymetrically, and starts to fall over sideways.

    Now, in order for it to "fall off" the side of the skyscraper, it would have to effectively pivot on one side of the building. This would require that at least half the mass of the (still intact) top portion of the building travel upwards, around the pivot point, before it could topple over sideways and land beside the building. There is pretty much no physical force that could cause this to happen.

    Look at the picture. It's obvious that there has been a massive structural failure on one side of the building. This has caused the top portion to pivot, as it is no longer supported on that side. Given that its mass hasn't been reduced (notwithstanding tunaman's alchemical theories), that means that all the mass of that top part of the building is being supported by one side of the structure. It shouldn't take too much of a leap of logic to conclude that that one side won't support it for long, and shortly after it starts to rotate, the whole support structure collapses, and the pancaking begins.
    The odd thing is though, that this part seems to just disintegrate as the rest of the building is falling, how could this happen unless all of the floors above the point of collapse failed simultaneuosly? Did it lean one way first, and then balance out somehow?
    It doesn't just disintegrate spontaneously, it falls down through the building and disintegrates en route. That's not visually obvious as it quickly becomes obscured by dust clouds on the way down.

    I never cease to be amazed by the people who talk about the top portion of the building "disintegrating" and "exploding", when the only clear visuals show that portion of the building intact up to the point where it becomes impossible to see what's happening to it.
    Why do i think these horrible, inconcievable things about that day? Because building 7 came down in a matter of seconds in the same manner as buildings 1 and 2. Charges would have taken months to plan, but no, "fire" caused it to collapse... yeah.. sure.
    I thought it was clear that massive structural damage as a result of two 110-storey buildings collapsing in an uncontrolled fashion right beside it caused it to collapse.
    You ask how no one noticed explosives being placed in 1 and 2? Why did they not notice 7? If it did indeed come down by detonation.... *cough*
    it did, of course it did!
    Did it? bonkey posted a 400-plus page document explaining why 1 and 2 collapsed. Have you read it? Unless you have a similarly well-documented argument for 7 being demolished, then I'm sorry, but I'm not just going to take your word for it.
    Lets just consider that it might "not look like freefall". Then why the hell did the speed of collapse not start off slow, and finish fast (lol, a bit like meself!)? I do believe it started off pretty fast, in both cases. In fact, each building came down in around 10 seconds.
    What does this prove? Do you have a scientifically valid case for saying that a spontaneous collapse of a badly-damaged 110-storey skyscraper couldn't possibly happen in 10 or so seconds?
    It should have took a few seconds more to get started at least.
    Why?
    Every floor just seems to fail simultaneously.
    It's perfectly visually obvious that the floors fail consecutively. Where the hell are you getting simultaneous failure from?
    The cores and floors below that were not affected by fire should have given some resistance even before the mass was substantial enough to crush the building.
    Yeah, the top floors were constructed from solidified helium. I mean, seriously: what is it about the top section of an enormous building that you guys consider too insubstantial to cause damage to the lower portion?

    Look, you would expect even just a little (i.e a tiny bit of, a few seconds) resistance from the lower floors at the start of the collapse. Obviously it was going to cause damage to the lower portion. 10 seconds is an unbelieveable time for them to come down.
    oscarbravo wrote:

    So the structural damage caused the whole building to crumble? You can see the penthouse part of the building fall first and then the rest following suit. See video posted earlier.

    A lot of folks say that the cameras didnt show the structural damage of seven that day because they were on the other side. Obviously, because of 1+2. But why did it fall straight down and not topple over? The "massive structural damage" that you speak of would have been on the side facing the ex twin towers right? Why didnt it fall that way? Or any other way?

    Remember now, this building fell hours after..... at 5.00 PM, nearly 6 - 7 hours after WTC'z. (source1) (source2) (differing times!) Source 2 says 7 collapsed from ancillary damage.....

    Should it not have fell almost straight away, considering the "massive structural damage"?

    Is it possible that the "massive structural damage" from the WTC's was confined to the very heart of building 7? It might have taken out the cores of this building (roffle).... and then we see... the new and wonderous "pancake effect"... for the third time ... in a matter of hours.

    You would think that they would have enough sense to explain this away by bad architecture, nope..

    The guy admits to "pull it" in an interview, it doesnt get any more obvious than that. Then he comes out and says he meant pull the firefighters!!! HA!
    What does this prove? Do you have a scientifically valid case for saying that a spontaneous collapse of a badly-damaged 110-storey skyscraper couldn't possibly happen in 10 or so seconds?

    Do you have a scientifically valid case for the building to come down in that time? Are we back to the pancake theory again? Oh ffs...

    The support structures of the towers were loaded to approximately 50% of their design strength before the aircraft strikes, if memory serves. Once the top of the building collapsed, that loading exceeded - by a wide margin - the stresses the structure was designed to handle. A massively overloaded structure doesn't offer resistance; it collapses.
    So the structural damage caused the whole building to crumble? You can see the penthouse part of the building fall first and then the rest following suit. See video posted earlier.
    ...which is precisely the same failure mode seen clearly in 1 & 2 - the top of the building starts to fall, overloading the rest of the structure, and the whole thing collapses.

    Tall buildings don't fall over, they fall down. Once they start to lean sideways at all, they lose the structural integrity that holds them up. Whatever sideways movement is visible, remember that the vast bulk of the force on a tall building is always going to be due to gravity - straight down.
    Remember now, this building fell hours after..... at 5.00 PM, nearly 6 - 7 hours after WTC'z. (source1) (source2) (differing times!) Source 2 says 7 collapsed from ancillary damage.....

    1 and 2 stayed standing for varying lengths of time after being hit by airplanes. 7 was hit by debris from 1 and 2, and was further damaged by fire. How do you reckon you have enough data to determine that it should have collapsed straight away?

    Someone, or lots of people? It just gives another, malicious viewpoint of why the buildings might have fell that day.
    But there is no dispute that the towers fell as the result of a malicious act. The dispute is over what that malicious act entailed, and insider trading does nothing except suggest someone might have known the airline industry would be effected....which again is not in dispute (except perhaps by those who think they were Global Hawks, loaded with explosives, and with holographic cloaking devices to make them look like Boeings...no, really.)
    Again bonkey, its my opinion, i am sorry if that still angers you. I was misinformed on the amount and quantity of samples they had available, thats all.
    Its your opinion and you're entitled to it. It doesn't make me angry that you hold it at all. I'm just pointing out that its an opinion based on ignorance of the many of the very facts that are being criticised.

    You question NISTs report, but (to date at least) have shown very little knowledge about what is in the detail of the report, how NIST carried out their investigation, nor how they arrived at their findings.

    You're still perfectly entitled to believe its a work of fiction...but surely you have to admit that unless you can show that you know what you're talking about its unlikely that others will ever find your position convincing.
    and also concentrated on what caused the collapse, more than the actual collapse itself.
    Isn't the entire dispute about what caused the collapse?

    I wasn't aware that there was any dispute over the suggestions that the buildings fell. Are some people are claiming they still stand and can be seen in the Manhattan skyline. ;)
    I think blueprints would have also stated if there was a problem in costruction in 1,2 and 7. Which there obviously was, particularly on that day.
    Are you aware that the NIST report has already had, and will continue to have, a serious impact on how high-rise buildings are designed in the future?

    Blueprints don't tell you about design-flaws. If they did, the design-flaws would have been spotted before the buildings were even built. Analyzing what caused the collapse initiation.

    As for building 7 - there are a number of points you seem to overlook in coming to your "flawed design" conclusion:

    1) NIST haven't completed their report on WTC7 yet...so I'm at a loss to understand what it is you're criticising them for about this building when they're still looking into it to make sure they do as thorough a job as they can.

    2) There isn't a commercial building in the world who's design incorporates resistance to large chunks of another building falling on it from 50 stories above.This was the initial cause of damage to WTC7. Are you suggesting that this is an obvious design flaw that would have shown up in the blueprints?
    It's falling over to a side!

    No, its not. Its pivoting as successive support columns fail from the point of impact (one corner) to the opposite. Once all support has failed, the pivoting ceases as gravity acts equally on both sides.
    Anyone would think that this part of the building would have tipped over and fell into the street below
    No...not anyone. Merely anyone who doesn't stop to think about the physics involved, or who doesn't have the required knowledge of physics in teh first place. Add to that anyone who is under the mistaken belief that single still photographs can give an accurate representation of the directions of movement.

    However, I'm delighted that someone has brought this point up again, arguing it just the way you have.

    You allege that anyone would think it would fall off the building. If I may be so bold as to reword your allegation, then one could say that common sense tells us that it will fall off the building and hit the path. Clearly, what you believe anyone would think, or what I have reworded as "common sense" is - in this case - wrong. It doesn't imply that some sinister external forces were at work, no more than it implies that the laws of physics decided to go on coffee break. It implies that common sense - what you see as what anyone would think - is wrong.

    Once you accept this, there are two things that should come out of it:

    1) Common sense and/or what anyone would think is not a reliable basis on which to judge complex collapse scenarios.
    2) We need tools other than common sense to back up an assertion before that assertion can have validity.
    The odd thing is though, that this part seems to just disintegrate as the rest of the building is falling, how could this happen unless all of the floors above the point of collapse failed simultaneuosly? Did it lean one way first, and then balance out somehow?
    OB has already explained this. His explanation is (unsurprisingly) consistent with what the official report says happened. Successive collapse from the corner of plane-impact caused "sagging" where one side started to fall while the other side remained supported. Once all support failed, sagging stopped as gravity affected both sides equally.

    In theory, were the "break off" portion large enough, its centre of gravity could end up outside the footprint of the building before the point where all connections between the top section and the rest of the building had severed. In such a scenario and only in such a scenario would it be expected for the mass to fall outside the building's footprint. Until the centre of gravity moves outside the buildings footprint, then it would require either a strong lateral force, or (as OB mentioned) that one side the building lift in order for this to happen. Thats not what happened - the top portion went exactly where the laws of physics said it should go. Whether or not common sense or what anyone would think agrees with them is only going to reflect on the correctness of common sense or what anyone might think in this case. It is not a reflection on the laws of physics.

    Wow, you love this report.
    I respect the report and the work that has gone into it. I see it as being a good example of what it is I respect about science. If you see my defence of this report as some sort of love-affair, then consider it a love-affair with science itself, and that I am protecting it from being ravaged by emotion-based reasoning that should have no place in determining what actually happened.
    Im sorry that i dont like it bonkey, you'll just have to get over that fact. Im sure it was conducted in good faith. Do i have to give evidence of contrary opinion about every subject to you?
    I don't care whether you like it or not. I care that you repeatedly use your dislike of it to suggest that its flawed whilst simultaneously showing you know little if anything about the contents of the report.

    If you stop trying to suggest its flawed, I'm quite happy to stop showing that you have no solid logical basis on which to base that argument.

    The report constitutes the fulfillment of BoP when it comes to the theory that airplanes and the resultant fire are what brought the towers down. If you want to refute that claim, then the burden is on you to prove the report wrong, either by showing there is something that it didn't explain or consider that can only be from a demolition, that its methods are flawed, or that its findings are demonstrably wrong. You can believe what you like, but at the end of the day you shouldn't be surprised that the cries of foul play fall on deaf ears from people who put science over belief when it comes to physical processes.
    Why do i think these horrible, inconcievable things about that day? Because building 7 came down in a matter of seconds in the same manner as buildings 1 and 2. Charges would have taken months to plan, but no, "fire" caused it to collapse... yeah.. sure.
    "Fire" didn't cause it to collapse. Massive structural damage caused by falling debris coupled with the resultant fires were the most likely primary causes.

    (ctd...)
    If you can prove to me that building 7 came down by fire or by any other means than explosive charges, then i'll consider the NIST report being sound!
    The NIST reports released thus far don't deal with building 7 in detail. They're still working on that report. Until its out, you're basically arguing that NIST must be wrong about 1 & 2 because they haven't finished the report on 7.

    What I can guarantee, however, is that the NIST report will not conclude that fire and fire alone was responsible. The only people making such allegations are people who already believe in something mor sinister and who want to construct a straw-man to attack.

    And please...lets avoid yet another iteration of someone holding up a snippet of the FEMA report's "conclusion".
    Other than that, you have to (you dont have to, but you might!) consider that 1 and 2 might have been brought down in the same unexplained and unbelievable way.
    Which unexplained way? THe only detailed explanation of any way about 1 & 2 coming down is what is contained in the NIST reports. As for it being uinbelievable - thats a personal belief based, as I've repeatedly said, on a severe lack of detail of what the explanation actually says.
    You ask how no one noticed explosives being placed in 1 and 2? Why did they not notice 7?
    I can't defend the as-yet-unpublished findings of what caused building 7's collapse....because they're unpublished and I therefore have no basis on which to judge them and no knowledge of exactly what it is I should be defending.

    Thus, with building 7 all I can do is judge any explanation on its flaws. Structural damage from falling debris coupled with ensuing fires is possible, but there are plenty of (as yet) unanswered questions about it. Demolition is also possible, but poses even more unanswered questions.

    On balance, I find the demolition theory far more unlikely based on the findings on 1&2. If someone can seriously challenge those findings, then the story changes.

    Concluding, however, that the findings for 1&2 must be suspect because of a belief in what happened to 7....thats putting the cart before the horse. It is - again - a case of putting belief over science when it comes to physical processes.
    Im sorry for having an opinion.. seriously, im sorry!
    Why? Because I disagree with it? You'd prefer if I kept silent? I don't get what all this apologising for is. You are as entitled to your opinion and the voicing of it here as I am to mine. I'm exercising that right, as are you. There is no need to apologise, unless you're trying some reverse psychology to make me out to be the bad guy for voicing an opinion.

    Should this forum just be left to those who agree The Man was responsible, so they can happily trade theories about what happened, whilst deriding the public in absentia for being mindless sheep believing in some cock-and-bull piece of fiction drawn up by lackeys who are all in thrall to the Powers That Be?

    If your approach is flawed, should I not point that out? Will it not - at the very least - show you why there is an overwhelming difference of opinion between those who adopt a scientic approach and those who don't?
    i was just thinking that these methods couldnt draw a totally valid conclusion.
    Those methods were not used to draw a totally valid conclusion, so I'm still at an utter loss to see what your point is here. Another straw man to attack?

    The methods you refer to were used to draw what valid conclusions they could. Other methods, such as materials analysis, modelling and testing were used to draw what valid conclusions they respectively could. All of these individually valid conclusions were then brought together, to produce a final overall conclusion which is in agreement with all of them.

    Below quote link (interesting, worth a read)
    Especially when you are dealing with the cores, which, oddly enough, are inside the building
    True. Now, if you'd care to comment about what NIST did, as opposed to saying that what they didn't do wouldn't have been valid had they done it....then we'd be getting somewhere.
    Lets just consider that it might "not look like freefall". Then why the hell did the speed of collapse not start off slow, and finish fast (lol, a bit like meself!)? I do believe it started off pretty fast, in both cases. In fact, each building came down in around 10 seconds.
    You believe it was about 10 seconds, or you can show it was about 10 seconds? I ask because shortened collapse-times are generally central to claims that the building fell too fast.

    See http://www.911myths.com/html/freefall.html for more details.
    As the mass from underneath got pulverised from the top, it should have contributed to the speed on the way down. It should have took a few seconds more to get started at least. Every floor just seems to fail simultaneously. With feck all resistance.
    The floors were being impacted with orders of magnitude more force than they were designed to bear. Their resistance before failure would be microseconds at best, and it certainly wouldn't bring the falling mass to a brief stop. Think of an articulated lorry hitting a brick wall. The lorry jars, but doesn't stop, and the wall doesn't "hold" for any appreciable amount of time.

    So yes, there was feck all resistance. Exactly what one would expect when looking at it scientifically.
    And i do retract my 4.5 second 7 collapse. The link i gave seems to suggest it was 6.4 seconds. Im sorry for this earlier remark.
    The following timeline is from the FEMA report. Its independantly verifiable, so the source I'm taking it from shouldn't matter. Either its right, or you can show its wrong using any of hte widely-available video evidence of the collapse...

    ~5:21:03 p.m. Approximately 30 seconds later, Figure 5-21 shows the east mechanical penthouse disappearing into the building. It takes a few seconds for the east penthouse to "disappear" completely.

    ~5:21:08 p.m. Approximately 5 seconds later, the west mechanical penthouse disappears (Figure 5-22) or sinks into WTC 7.

    ~5:21:09 p.m. Approximately 1 or 2 seconds after the west penthouse sinks into WTC 7, the whole building starts to collapse. A north-south "kink" or fault line develops along the eastern side as the building begins to come down at what appears to be the location of the collapse initiation (see Figures 5-23 and 5-24).

    Your 7-ish second collapse-time is, from every place I've seen it, measuring only the time after 5:21:09 before the structure had finished collapsing. IN otherwords, it leaves out 6 seconds of the collapse - tupically using hte same type of flawed logic that claimed that because the front wall of the building was in decent shape, there couldn't have been serious damage to any of it anywhere.

    One can read this as follows - either the collapse took 6 seconds plus your measured time, or your measured time doesn't take into account prior internal collapse which there is evidence for and which would explain why there was so little resistance in your time-window....or that the FEMA timeline is correct and that the entire outer structure collapsed in 1 second giving a total time of 7-ish seconds.

    I'm pretty certain we'll agree the last option is toss. Whether or not you'll accept the other figures depends on where you define the collapse-initiation...when the walls start falling, or when the first signs of collapse begin 6 seconds previously.

    One hypothesis suggests most of the interior collapsed before your clock started ticking, and therefore the observed 7-ish seconds is bang-on what one would expect to see when walls collapse with no building to hold them up. It also allows the walls to fall slightly inward whilst preserving the illusion of falling "straight down".

    But again...I'll wait till the final report is out before deciding how good or bad a job NIST do in explaining it rather than condemn them in advance.

    Oh look - the link OB posted earlier today matches pretty-much exactly the hypothesis I suggested. Internal collapse, followed by hollow-shell collapse. The latter takes approx 7 seconds.

    When is the NIST report for building 7 coming out?


  • Advertisement
  • Closed Accounts Posts: 463 ✭✭tunaman


    Oscar and bonkey, seeing as you are both singing from the same hymn sheet, there seems no point in replying to both of you seperately.

    You claim I have not looked at the official NIST report, which is wrong, but it hasn't stopped you accusing me of not knowing the official story, which is also wrong.

    I pointed out that the 9/11 commission claimed the south tower collapsed in 10 seconds, which is way out according to bonkey and his precious 911myths site, which tries to claim the collapse took more than 15 seconds.

    So if the claim of 10 seconds from the US government is so far out, then how can you possibly claim their collapse time for building 7 is accurate?

    As for looking at the damning evidence supporting the demolition theory, bonkey has twice ignored the documentary 911 eyewitness, which should appeal to both of you, as it is very scientific. Bonkey also claimed that no audio of any explosions were caught on tape, yet when I presented this documentary as proof that he was just blatantly wrong, he ignored it.

    So here is a link again for the third time...

    http://video.google.com/videoplay?docid=-3498980438587461603&q=911+eyewitness

    I know the evidence presented here is incredibly incriminating, and must be very hard for you guys to try to explain, but give it your best shot. :)

    Here again is the slow motion clip of the top of the north tower. For a start notice the incredible symmetry of the collapse...

    http://img154.imageshack.us/img154/1199/ntower8gc.gif

    This should make it easier to see how the top 18 floors disintegrated, before they had a chance to pancake down on the floors directly below...

    As for building 7, where is the raging inferno?

    The official report should be able to tell us all what happened, right lads?

    According to NIST they need to do more investigation, and the final report will be out at a later date...

    Amazingly NOT one piece from building 7 was ever examined before it was cleared up incredibly quickly...

    http://img82.imageshack.us/img82/5530/wtc7cleaned1ag.jpg

    Is it just another coincidence, or did they have something to hide?

    Strange how the 9/11 commission never even mentioned the collapse of building 7...

    What about able danger?

    I'd be inclined to believe you if you could demonstrate a familiarity with the report.

    You repeatedly claimed that NIST didn't even consider alternate options, without once mentioning that they must have considered them at least enough to know which ones to say they found no evidence of in this report. When I gave you the hint, you quietly changed your insistence that they didn't as much as consider the possibilities to a bet that they didn't really put much effort into it.

    You've made several such inaccurate claims about both the report and the "official story" (which in itself is a vague and misleading term). So claim that you know this stuff all you like. I'll believe you when you start representing it accurately and stop making claims to the effect that you're not going to look at it just before posting verbatim quotes from it.

    This doesn't mean you have to agree with it, mind you....just that you show that you know what it is you're disagreeing with and that you represent it accurately. Or would you rather that I believe you do know what the content is and that when you make inaccurate or misleading statements about it that you do so deliberately????
    I pointed out that the 9/11 commission claimed the south tower collapsed in 10 seconds, which is way out according to bonkey and his precious 911myths site, which tries to claim the collapse took more than 15 seconds.

    I've repeated more often than I care to count that I believe there are inaccuracies and omissions in the various reports. I have never defended the claims of the 9/11 Comission, let alone this specific claim of theirs. So what has led you to believe that I put any weight behind this particular claim is beyond me, especially when - as you point out - I've supplied sources which contradict it.
    So if the claim of 10 seconds from the US government is so far out,
    Its the claim of the 911 Comission, not of the US government. Is accuracy too much to ask?
    then how can you possibly claim their collapse time for building 7 is accurate?
    Firstly and foremostly because it is a claim that is verifiable through direct analysis of commonly-available material such as video.

    I've verified (to within about 1/2 a second) to myself that these figures are an accurate of what can be seen to have happened.

    If you believe they're wrong, all you need is one of the myriad of collapse videos that you've bombarded us with over the months, a stopwatch, and enough self-honesty that you won't fabricate the results to suit yoruself. Oh - and you also need the will to put a bit of actual effort into research rather than simply choosing to believe sources that tell you what youwant to hear.

    Secondly, unless you're suggesting that a single figure that I disagree with makes all other information in all other reports by all other seperate groups automatically incorrect, then I've no idea what it is you're arguing. After all, I reproduced information from the FEMA report, not from the 911 Commission report. I even said as much. Were you under the mistaken impression they were the same thing? Or could it be that you're not familiar with them as seperate reports, despite not believing either?

    The FEMA report also maintains that these events occurred on September 11th. Do you believe that too is wrong? Do you believe, in fact, that the Twin Towers are still towering in the Manhattan skyline and that comments to the contrary from "The Government" are wrong?

    I'm hoping that even you would find such assertions to be bordering on lunacy. So please...give up with this notion that simply because something is in a governent report, it cannnot be trusted, and that even if independantly verifiable it should still be assumed to be wrong rather than tested.
    As for looking at the damning evidence supporting the demolition theory, bonkey has twice ignored the documentary 911 eyewitness, which should appeal to both of you, as it is very scientific.
    I've already explained why I've not commented on this. I've no interest in repeating myself simply because you choose to ignore this fact.
    Bonkey also claimed that no audio of any explosions were caught on tape,
    Thats not what I claimed....but please...continue showing that accuracy isn't really a key consideration when you build your arguments.

    Hey - I know - why not quote a portion of what I said, so that when taken out of context it will back up your claim....that would be a really convincing way of showing that you've got a point.
    For a start notice the incredible symmetry of the collapse...

    I guess an explanation as to why you believe symmetry is suspect is too much to ask for? It is, after all, what one would scientifically expect.

    Hmm...wait a second...maybe I can explain why its suspect...

    The government fund scientists, and those scientists say symmetry is what one would scientifically expect. so its what the government would want us believe, so it must be false!!!! Not only that, but no other qualified scientist contradicts them, proving that the government has them all under its thumb.

    So because science says it should be symmetrical, we can take it that it shouldn't be, and that symmetry therefore is proof that the entire thing is a coverup!!!!!

    How'd I do? I know I didn't mention common sense in there, but, well, I'm not as good at formulating these ideas as some, given that my forte is more on the logical side of things.
    This should make it easier to see how the top 18 floors disintegrated, before they had a chance to pancake down on the floors directly below...
    We've had this conversation. I see no need to repeat myself just because you restated your scientifically-invalid beliefs and added a shiny new picture without ever dealing with the explanations I and OB have offered other than to make it clear that you disagree with science.
    As for building 7, where is the raging inferno?
    We've had this conversation too. Just because its buried back in earlier pages doesn't mean it suddenly ceases to exist.
    The official report should be able to tell us all what happened, right lads?
    Hopefully, yes. When it comes out.

    Thats why they're taking their time, involving external independant companies, having said externally-contracted work reviewed by independant third parties and so on. Its because they want to be able to tell us what happened to the best of their ability, rather than stop while there's unanswered questions they believe they can answer.

    Isn't that strange though....they're involving all the types of non-government people you always complain haven't been involved. No doubt these so-called independant people will "obviously" have been bought off. I mean...its the government who's paying them. Unless, of course, they find something that suits your argument....then they'll be paragons of virtue.
    According to NIST they need to do more investigation, and the final report will be out at a later date...
    And your problem with this is what, exactly? Do you want less investigation done? Maybe you object to them contracting some of it out to non-governmedn bodies and the involvement of third-party reviewers?
    Amazingly NOT one piece from building 7 was ever examined before it was cleared up incredibly quickly...
    And you know that nothing was examined prior to cleanup....how, exactly?

    A picture showing they cleared up quickly says nothing about whether or not anything was examined beforehand...but its an established pattern to see you using a picture as "evidence" of something it does not and cannot support, so its hardly surprising.

    And of course, no-one could have chosen and removed samples prior to cleanup for use in investigations when needed. Thats just crazy-talk, right?
    Strange how the 9/11 commission never even mentioned the collapse of building 7...
    What is strange is the complete lack of a coherent argument showing why they should have mentioned WTC7 - how it fit into the scope of what they were tasked to do.

    But again...I don't ever recall defending the 911 Comission report nor what it does and doesn't cover, so I can only assume this isn't aimed at me.
    What about able danger?
    ...
    What about all the war games on the morning of 9/11?
    What about them? Do you have a new point to make or are is there some other reason you're re-intrroducing the same tired old points?
    Incredibly the general in charge claimed the war games actually enhanced their ability to respond...
    And? A crash-helmet will enhance your ability to survive a crash. You can still die in a crash while wearing one.

    Incidentally, this guy is a general, so he works for The Goverment. Doesn't that make him automatically a liar and co-conspirator in your book?

    Should we now believe what some employees of The Government say, despite you asking me in the same post how I could believe something because it was from "the government"!!!!

    Hmmm...

    Evidence backs up tunaman's beliefs ==> credible, regardless of source
    Evidence contradicts tunaman's beliefs ==> not credible, especially if its from the government, regardless of whether or not its scientifically testable.

    Thats presumably just a coincidence though.

    Just to go back and pick something out:
    Correct me if I'm wrong, but as far as I know structural engineers are not experts when it comes to buildings collapsing...

    Tunaman, you're so wrong it's not funny, and if your claims had any shred of credibility left prior to that statement, it went bye bye.

    I actually took time out and sat through that. There's an hour and three quarters of my life I'll never get back.

    I'll post just one image clipped from that video:

    911-1.jpg

    This is taken from the section where they explain why the pancake theory is impossible, because of Newton's laws of motion. They tell us that if the top of the building started to fall sideways, it must have landed in the street. To illustrate this, they use the schematic above, which clearly shows the top portion of the building toppling in such a way that one corner has risen way above its starting point (I've added the red line to illustrate this). This is clearly completely different from what actually happened, apart from being physically impossible.

    This is the standard of "science" used throughout the video. Other examples include overlaying a parabolic arc on a freeze-frame of a debris cloud, completely ignoring the fact that the cloud itself is falling, as can clearly be seen when the video is playing, and measuring an approximate 100m difference between the height of WTC7 and a neighbouring building (with no regard for parallax) and using that as the basis for "proving" that the building fell faster than freefall.

    What a load of crap.

    "Obviously" its using an advanced form of scientific modelling that you just don't understand.

    This is taken from the section where they explain why the pancake theory is impossible, because of Newton's laws of motion. They tell us that if the top of the building started to fall sideways, it must have landed in the street.

    From such an argument, only the following conclusions are logical (that I can see)

    1) The top of the building didn't fall sideways in the manner portrayed, as it didn't land in the street.

    2) The top of the bulding fell sideways and landed in the street, despite all the evidence to the contrary.

    3) Newton's laws of physics are wrong.

    Of these three logical conclusions, only one actually would undermine the pancake theory - that being option 3.

    Don't get me wrong - option 1 would allow the pancake theory to be wrong. It would also allow it to be correct. Concluding "this model is not what happened" doesn't tell you much about what did happen, other than that its not whats in your model.

    I tried to watch the whole thing from start to finish at the weekend. When he got to helicopter 4, I went and checked some other sources and saw that the author never cross-referenced his "reverse angle" camera work with other footage, where it is clear that many of his seperately-numbered helicopters were the same choppers flying in and out of shot.

    At that point, I jumped to a few bits here and there. When I saw the positive-parabolic "proof", I gave up. It is abundantly clear by then that when tunaman described this video as " very scientific", he was either having a laugh, was deliberately trying to mislead us, or simply has an irreconcilably-different opinion to me (at least) as to what "scientific" means.

    Or perhaps what he meaant was that the video dresses its arguments up in pseudo-science to make them more credible-sounding. I'd have no argument about such a claim, had that been what was made/meant.

    Thought experiment once more (and I'm directing this at those who, unlike tunaman, seem to have some interest in the actual physics of the event). Whether caused by jet-fuel and office-furniture fire, or by any other means, imagine that a catastrophic structural failure has occurred as indicated in the photograph you posted. The top half of a huge 110-storey building collapses assymetrically, and starts to fall over sideways.

    Now, in order for it to "fall off" the side of the skyscraper, it would have to effectively pivot on one side of the building. This would require that at least half the mass of the (still intact) top portion of the building travel upwards, around the pivot point, before it could topple over sideways and land beside the building. There is pretty much no physical force that could cause this to happen.

    Look at the picture. It's obvious that there has been a massive structural failure on one side of the building. This has caused the top portion to pivot, as it is no longer supported on that side. Given that its mass hasn't been reduced (notwithstanding tunaman's alchemical theories), that means that all the mass of that top part of the building is being supported by one side of the structure. It shouldn't take too much of a leap of logic to conclude that that one side won't support it for long, and shortly after it starts to rotate, the whole support structure collapses, and the pancaking begins. It doesn't just disintegrate spontaneously, it falls down through the building and disintegrates en route. That's not visually obvious as it quickly becomes obscured by dust clouds on the way down.

    You were right on track with your physics until you said the top section would rotate back level. What should actually happen is the top section would continue to rotate to horizontal, in fact rotation to horizontal would increase in speed. Yes there is more weight on one side, but remember there is less on the other. Those floors having less weight above them wouldnt be breached as quickly as those on the heavier side.

    ...except that I didn't actually say that.

    If the top section was freefalling and rotating, then yes: it would continue to rotate until it hit the ground. But it wasn't freefalling, it was collapsing into a steel-and-concrete structure.

    It's all too easy to predict a nice clean sequence of events based on a solid-state model with lots of smoothing-out assumptions. For example, your argument presupposes that the top section remains intact as it falls. Going back to the thought experiment of dropping a small skyscraper onto a big skyscraper: do you really think the small one will stay intact for very long?

    When did i say it was freefalling?

    It's BECAUSE it was collapsing into steel and concrete that you should be able to apply Newton's laws to it. What I'm saying is the fact that it did not continue rotating (because of the resistance of the steel & concrete) that this cannot be reconciled with Newton.

    Also your previous claim that half the building would need to "travel upwards" in order for the top section to fall into the street is pretty weak. The tower first started falling straight down and then started rotating. Have another look:

    Probably about the same time I said it rotated back level. ;)

    Assume a spherical chicken of uniform density...

    You've assumed a very specific reason for the observed rotation, and assumed that the forces involved remain constant throughout the collapse. Have you read the NIST report?

    I was refuting tunaman's "scientific" film, which - as illustrated in my screenshot from it, shown above - made precisely this claim.

    Your first link is a schematic diagram, which doesn't provide any information. The second link is to a video clip which doesn't illustrate what you say it does. Having watched it several times, as well as clips from other angles, it looks to me like the rotation was the first stage in the collapse. But then, there's only so much that can be determined from a quick look at a video clip, which is why I set more store by the NIST report than by any conclusion drawn from a single visual source.

    You don't refute, I assume, that the top section did indeed rotate? I have'nt assumed any reason why it began to do so and the reason why it did is not the issue here. Once in motion it must follow Newton's laws.

    Not for those unwilling to see it, correct.:rolleyes:

    And you are correct the forces were not constant throughout the collapse, which partly explains why the top didnt continue rotating. There were other forces at work here. That much should be apparent. What all those forces were I'm certain our opinions differ on. The ones you claim them to be are insufficient to explain the observations, whether you can understand it or not.

    There's no simple answer.

    Rotational momentum should be preserved in freefall, so had the top somehow fallen over the side and fallen down, it should have continued to have some rotation around its centre of gravity. We should bear in mind, however, that in the absence of a secured fulcrum, the rate of rotation would be far far less.

    However, as has been accepted by both sides, no-one is suggesting it was in freefall. It hit the lower portion of the building. It hit it at an angle - some leading edges of rotation will have encountered resistance that acts counter to the rotation.

    To be able to say whether or not rotation should have continued isn't easy. A lot would depend on the angular momentum taken against the resistance offered by the building.

    The angle of the upper portion of the building on impact would also have determined how much more rotation would be required before the distribution of mass would assist further rotation as opposed to retarding it with relation to the resistance of the impact with the building it was collapsing on.

    Lets not also forget that upon impact, a new fulcrum is added to the problem. Initially the top portion would have been rotating around a fulcrum at one edge or corner. Then its in freefall briefly, now rotating only around its centre of gravity. Then its "leading" edge/corner impacts the lower building, and there's a new fulcrum.

    This all effects the rotational momentum, as do oh-so-many other factors.

    I wouldn't like to have to work out the math, personally.

    I can say. however, that its by no means an open and shut case to argue that physics tells us that what we saw was somehow inexplicable under the official explanation.

    Of course not.

    In simple terms: once something starts to rotate, it will continue to rotate unless a force acts on it to prevent it rotating. No argument there.

    I'm taking issue with the rest of your assumptions. You seem to be assuming, for example, that the assymmetry of the structural damage that caused the initial rotation stopped being a factor as the collapse progressed; in other words, that there was no further assymmetry in the progress of the collapse that could have acted to reverse the rotation. You also assume that the top portion of the building remains essentially intact as it falls, in order that the centre of gravity will behave neatly as modelled.

    My point is that there are myriad forces acting on the top portion of the building as the collapse progresses.
    Not for those unwilling to see it, correct.:rolleyes:
    Allow me to rephrase: The diagram doesn't yield any information as to whether the building started to fall before it started to rotate, or vice-versa.
    And you are correct the forces were not constant throughout the collapse, which partly explains why the top didnt continue rotating. There were other forces at work here.

    Educate me: what sort of forces would be necessary to explain the observed collapse (bearing in mind that the collapse becomes quickly unobservable due to the dust cloud)?

    So you'd agree that a new independant investigation should be carried out to make it an open and shut case once and for all, which is the way in which an investigation in to something like this should be done.

    Yes, it's been discussed in this thread already. It barely contains a nod to the discussion we're currently having, but it does include this: "this block turned mostly to powder in mid-air!" I'd love to know what he bases this on.

    I neither agree that one should be carried out, nor that it should have been done in the first case.

    It is not the job of an investigation to conclusively prove that nothing unusual happened in every instance where someone points and says "thats not right".

    The onus is on those saying that there is something in need of investigation to show that it is, in fact, in need of investigation. School-level-physics-guy saying "I dont' believe 16 floors falling on the rest of the building would have collapsed it" doesn't make the collapse itself exceptional, particularly when you consider that lining up against him is pretty-much every structural engineer consulted or known to have offered an opinion.

    Similarly, someone saying "the roof should have rolled off and onto the street" doesn't mean that it is so. Instead, it suggests that someone with no demonstrated relevant qualifications doesn't think it looked kosher. If experts agree then it should arguably be checked further. If experts don't agree and say "no - this is perfectly in keeping with what one would expect" then one has to wonder both why further investigation should be obligatory and who is expected to carry it out.

    Think about it - if the experts say in advance that there is nothing evenly possibly sinister that needs careful modelling...who exactly is going to do the modelling?

    And lets not forget that part of the expertise that these people have is in knowing when something needs to be looked at closer and when more general assumptions are reasonable. People would generally trust their doctor when he tells them that no, they don't need to have an expensive test to rule out the possibility of some rare illness. And if one can't find any doctors who'll say that the test is necessary do you really think that the opinion of a car mechanic is what one should be listening to instead?

    Where do we draw the line? When do we accept that people who know how to analyse these things have done so and concluded that there is nothing sinister in what we are seeing. Their work has been scrutinised by other experts who haven't said the assumptions are unwarranted. Upon publication, the reports in question have been widely read in the relevant fields - particularly as they will dircetly influence building design in the future. Again, upon reading the NIST report, not one expert has said "hang on...this doesn't hang together". Not one expert. Not one American, pro- or anti- the Government. Not one non-American expert from a pro- or anti-American nation. Noone except people who lack the expertise necessary to actually show their opinion is solidly grounded has criticised the model either for its content or for what it didn't contain.

    My main grounding is applied math. I know the type of modelling that would be necessary, and that it would be a seriously complex job. What I lack is the expertise to offer a solid opinion without a model of what should have happened. So while I can understand the math, I also know I could neither predict whether or not a model is really needed, nor could I say whether or not the model was accurate at thee end of the day.

    Just as I don't listen to a car-mechanic for my medical advice, I'm gonna listen to the experts on this one too....until such times as someone can mount a credible challenge to their assertions.

    So - what, exactly, are your qualifications that add such weight to the allegations that the thing would have rolled off? Are you a doctor offering medical advice, or a car-mechanic doing the same?

    Note - I don't rule out the possibility that all the experts are wrong and the car-mechanic is right. However, when faced with the choice of either testing every hypothesis of every car-mechanic, taxi-driver and other non-expert who offers their opinion of what happened, or insisting that unanimous expert opinion carries more weight in the absence of a model....I do not believe that one can seriously go with the former. The third option would be to give credence to some of the opinions of some taxi-drivers and car-mechanics. Of course, this then begs the question of who should decide which opinions should be listened to. It can't be the people qualified to judge, because we've already decided we're not listening to what they say...so who does that leave us???!!!!???

    Einstein was a patent clerk. If he came out and said "I believe Newton is wrong", no-one would have listened to him. Instead, he came out and effectively said "Newton is wrong, here's why, and here's how it can be tested". He had a model which made testable predictions. Even then, he was laughed at by many experts in his field (many, but not all, lest someone fail to note the distinction). However, his model stood up to scrutiny, his tests were carried out and observation matched his predictions and differed to those arising from Newtonian physics.

    If you want your "the roof would have fallen off in the absence of some unknown force" theory to be taken seriously, then do what Einstein did. Produce a model. Get some experts to agree with you. Propose tests which would falsify either your alternate conjecture or the supported one. At that point, a case could be made that the system would be at fault not to consider your point of view.

    Until then, you're a car-mechanic telling me to ignore what all the doctors tell me cause you know what's really wrong with me.

    It's amazing how this is actually still being discussed. It goes to show that many people still do not understand what happened that day. Disgrace so it is.

    If it happened in Ireland, you would be correct that the job of an investigation is not to prove that nothing unusual happened, when someone has a question. However this is not the case in the United States. The first amendment to the constitution give american citizens the right to petition their government for answers which must be answered to the best of their ability. Thats what their government is their for, they are servants to the people not the other way round. We don't have the same rights here as they do over there.

    So how many experts do you think is required to say that the official story does not answer sufficiently the questions that people have the right to expect an answer to. Scholars for 9/11 truth now have over 300 members, more than 200 of which have advanced research skills and over 85 with academic affiliations or equivalent, tack on the 36% of Americans who believe that the US aided in the attacks (http://www.nypost.com/news/nationalnews/one_in_3_americans_say_u_s__aided_9_11_nationalnews_thomas_hargrove______and_guido_h__stempel_iii.htm) and the recent story that the 9/11 Commision themselves suspected that the Pentagon were deceiving them in their testimony (http://www.washingtonpost.com/wp-dyn/content/article/2006/08/01/AR2006080101300.html?sub=new) and its apparent that a new investigation is warranted.
