Malaysia Airlines flight MH370-Updates and Discussion

homerjay2005

has the search attempt been scaled back or it is still at original levels?

the fact no debris has turned up, is incredible.

Interesting post from the *updates only* thread :

Two interesting pieces of news:

Experts are to look again at the flight path calculations of flight MH370.

The data from satellites and radars was examined, first giving a huge arc that stretched from Kazakhstan all the way down to the southern Indian Ocean.

That was later narrowed down to the current search area which has already seen 4.6million square kilometres of ocean scoured.

Angus Houston, head of the search, said: "We've got to this stage of the process where it's very sensible to go back and have a look at all of the data that has been gathered, all of the analysis that has been done and and make sure there's no flaws in it, the assumptions are right, the analysis is right, and the deductions and conclusions are right."

Archaeologist and writer William Meacham pointed out one significant point why the Australian led search was returning zero results.

In essence, Mr Meacham thinks that the pings on which Australia based its decisions on MH370 were coming from satellite trackers tagged to marine animals found in Australia.

"For several decades, pingers with frequencies of 30 to 50kHz have been commonly used to track large, deep ocean animals. Location and other data is transmitted to receivers in the ocean or to satellites whenever the animal surfaces. Acoustic pingers are also widely used as fishing net protectors, to drive away predators that would steal fish," he wrote.

Various governmental projects in Australia had employed tagging marine animals with satellite trackers.

The 'pings' thought to have emanated from missing Flight MH370's black box recorders might actually have come from satellite tracking devices tagged to marine animals such as sharks and turtles, it has been claimed.

The suggestion, put forward by archaeologist and writer William Meacham, raises the prospect that search authorities are looking in the wrong place for the plabe, which disappeared on March 8 with 239 people on board.

Writing in the Malaysian Insider, Mr Meacham, who is affiliated with the University of Hong Kong, said: "For several decades, pingers with frequencies of 30 to 50kHz have been commonly used to track large, deep ocean animals.

"Location and other data is transmitted to receivers in the ocean or to satellites whenever the animal surfaces.

"Acoustic pingers are also widely used as fishing net protectors, to drive away predators that would steal fish."

On the first point, it's pretty logical at this stage to re examine all of the information thus far, considering that no trace of the aircraft has turned up and it's been so long. Makes sense to check all the data again and be sure as they can be that they aren't wasting time looking in the wrong place.

The second point is interesting. Could explain why the Chinese picked up a signal so far from where the Australians did when the first signals were heard.

There has been a lot of debate over on pprune about the reliability of the doppler shift analysis and inmarsat data too. It is becoming more acceptable (elsewhere than this thread) to consider the northern arc, it seems.

How on earth is an archaeologist qualified to make such pronouncements about the pingers. Jesus its ridiculous. IM more qualified to be an mh370 pundit than he is, and that's not saying much. :rolleyes:

Synode

Is it a reasonable explanation for the pings? Any experts?

Happyman42

If these tracking devices on marine animals are broadcasting within the same frequencies then it sounds reasonable.

Because he's an archaeologist he can't possibly know this stuff?

Various governmental projects in Australia had employed tagging marine animals with satellite trackers.

Maybe he worked on a government project involved with this stuff, or worked with people who were.

Maybe it's nonsense. But even if it is, his profession is still irrelevant.

But these signals have since disappeared - so they assume it's the pingers battery dying , if it were marine animals surely they'd still be hearing them ?

or maybe they aren't listening anymore... my personal opinion is the plane will be found ... but could take a decade..

If it was marine life tracking tags that they picked up then they aren't being heard because they are constantly changing location.

Back to the drawing board and a revision of all the possibilities.

If its whales or suchlike that are tagged ,then theyre unlikely to be in the same area for long. These tags only have a 2 or 3 km range AFAIK so you have to pretty much right over it to detect it.
The frequency range of the animal tags is between 30 and 50 kHz. The plane pinger was on 40 or 45 kHz I think.

AFAIK it was 37.5 KHz and the signal received was exactly that ..

Ah OK. I was going by early news reports which varied.

Having read that thus far only Bangladesh navy ships had gone to investigate the GeoResonance claims, he said: “As far as Bangladeshi Navy checking our findings, we firmly believe that our findings have not been checked at all.
“The media mentioned ‘three Bangladeshi ships scouring the Bay of Bengal’. However, what does ‘scouring’ mean?
“We reported the precise location. Given the margin of error, the reported area size was only 500 sq metres! What was required is to send just one ship to the specified coordinates and check the location with a sonar.
“GeoResonance remains quietly confident on our reported finding in the Bay of Bengal.
“We are considering verifying the location ourselves. Two words to all the sceptics: ‘Test us!’”

Difficult to know what to make of this GeoResonance claim..... Why would they not investigate it?

Like one of the comments: "Well they should put damn animal pingers on the planes since they seem to work much better than a black box right?"

I still think people are totally underestimating the vast area of sea that needs to be searched, even after numerous articles mention it specifically.
http://uk.reuters.com/article/2014/05/10/uk-malaysia-airlines-idUKKBN0DQ03U20140510

These searches take time, a lot of time and the areas involved are huge.

My gut instinct was that they are just shilling their business tbh. Obviously if it was followed up and nothing found they'd look bad but maybe they're willing to risk it for publicity.

So there is a book out already, called Flight MH370: The Mystery the author reckons plane was shot down in a military exercise.

I presume it's listed in the 'fiction' category.

Such Twaddle ..

Cashing in on this, media no at this stage this is a recovery op that will take at least months - probably years to solve - but they will find it.

Forgot about this. Whats the latest or is the trail dead?

Theboinkmaster

I don't think they'll ever find it.

NipNip

We will never know what happened to this flight.

kippy

Wreckage or physical evidence of the plane WILL show up and it's shell probably will be found at some point in the future, we may, however, never know exactly what happened to get it to that point.

the_monkey

Patience, as said before by investigators - this is a story that will take months - probably years to find the answers.

Its not like whats the latest on Chelsea,Man City etc.. signing Diego Costa, - there are no daily updates.

One day a couple years from now we will see a newsflash on the subject.

and the Black Box data will put a rest to the ridiculous conspiracy stores out there.

Apparently they will release the satellite data for independent analysis.

Put to rest the CTs, or validate one of the less outlandish ones. The whole event is as
nonsensical as it first appeared, and the flash oxygen fire theory on pprune is as unsatisfactory as other theories really.

The data is being prepped for release as I understand, it will be interesting to see what other analysts make of it.

I'm on phone so can't provide links, but if you follow the pprune thread you will be aware that this is partly incorrect, as some pings received have been pretty much officially discarded, with a frequency of 27 and 33KHz, leading the searches further North if I understand right, nearer to where the Chinese handheld underwater mike pings were heard ? I could have misunderstood which pings are still considered valid or
not.

Edit : think I have the geographical refs wrong

That's interesting that they would refuse to hand over such data....
