A Malaysia Airlines Boeing 777-200, flight MH370, has lost contact whilst flying from Kuala Lumpur to Beijing.

(Am I doing this right?)

There are so much rumour and innuendo rolling about on this in reality, Who Knows? must surely be the current answer. I personally still favour the anoxia theory primarily because so far as I know that seems the most probable and least inventive.
too much evidence it didn't happen

Assuming for a moment the wreckage is found, I think it will, but will take a long time, how much information will be recoverable from the FDR and CVR?

As is once they are in the water and the batteries are flat, how long will the unit survive sat on the sea bed and still give up useful data when recovered.

Air France 447 was underwater at extreme depth for nearly 2 years before the flight recorders were recovered and data retrieved.

They can last pretty much indefinitely underwater, the bigger concern is actually finding them.

I wondered that. Thus far it would seem not a lot.

Inmarsat pings are considered hard evidence, as it's not really plausible someone could use another plane with the same transponder to fake them along the way.

From memory there was a Colombian plane that smashed to pieces in the mountains and was not found for over 20 years.
Do you mean "Stardust" in 1947? That was, and still is, a story im fascinated by. The plane actually hit the top of a mountain and sunk into the snow and ice. It was 50 years before the wreckage worked its way down the mountain inside a glacier, much of it (and some parts of the humans) very well preserved, and was then found thawed out.
But while that 50 year old mystery was solved, the final piece isnt - why was the word "STENDEC" repeatedly transmitted in the moments before the crash?

If you wanted to read up about this story, why not listen to Willie Nelson performing his classic song "Stadust" while you do? Its nothing to do with the plane, but i like to pretend it is...
There's an old BBC Horizon documentary about this incident currently on iplayer.

And they indicate nothing more than vaguely where it headed and how long it was in the air for.

The solid state memory in the recorders is both incredibly robust (i'd imagine a 25year data retention time minimum unpowered) and it is designed to be "sealed" Ie the actual memory chips are completely "potted" on a pcb that is housed in an extremely strong metal cylinder that has glass sealed hermetic "pass through" connectors for the data. That means, even when unpowered, and under extreme pressure it will take a very very long time indeed for any damage to occur to the memory cells. Without any compressible pockets of air (except for micro fissures in the silcon die encapsulation) external pressure is simply transmitted straight through the device as if it were a solid object.

Thanks for that. Pretty much what I imagined, but wasn't sure.

quite enough to narrow the huge search area into a still huge search area, heh

I haven't continued to follow this thread.
Could someone fill in some gaps fro me here (or correct my memory):

As far as I know the plane took off and was travelling north.
They have since found signs of it somewhere significantly south of where it set off (despite the fact it had set off going north.
THey have no idea whatsoever as to why it ended up where it did.


Is the above more or less right? Have they actually found specific debris they can attribute it to or not?
Is there a best theory yet?

no debris at all, if Inmarsat is to be believed the plane sunk some thousand miles west of Australia

I think it's safe to conclude it was a hijack which involved pilot(s) because only they could execute a low-terrain flight over malaysian mainland to evade radars, maybe they were instigated by someone maybe it was his/their own decision for whatever reason.

It's far from safe to assume anything. Little strong evidence at all so far so assumptions are based on very flimsy info.

What we know beyond reasonable doubt:

1) the plane is lost.
2) the crew and passengers are dead.



What we don't know:

3) everything else

Are you adding this to all your other theories of what definitely happened?

pprune thread has some disturbing info re releasing of information pertaining to immersat and underwater pings to the representatives of the bereaved.
