I read something the other day about a flight recorder on a private jet jettisoning itself when if felt a certain amount of g force, had parachute/beacon/inflatable stuff for when it landed.

Real, possible, or made up rubbish?

The principle behind the homing beacon on the black box is that you already know roughly were it is because it's surrounded by wreckage, separating the black box from the airframe would normally make it harder to find. Not that finding the wreck or the box is normally the problem, this is a very unusual case.

If you were to go for some system that automatically jettisoned a black box under certain circumstances, surely one of the parameters you would make sure it recorded would be the aircraft's position at the time of impact ? No matter how far the box then drifted it would provide information allowing the wreckage to be found.

Other way round. Airframe big = easier to find, then you're looking for a black box in a small search area. Jettisoned black box = small = difficult to find.

Nope - aircraft wreckage at bottom of the sea v. floating box with radio beacon & strobe light - I think I know which would be easier to find

After the batteries die ?

[jmorgan]

Well, if you want then a box that emits a beep, low power usage, searchers looking for beep, beep back within a certain range and the strobe goes off.

To be fair either will be damned difficult to find if the aircraft wasn't on its planned route, floating becons would be OK if they where picked up very quickly otherwise they could end up accidentally sunk or drifted miles. On the bottom they should stay fairly well put just hard to get too.

10 weeks in and some knob jockey has released a book on MH370 to cash in. wker

Meanwhile the families lawyer up and Malaysian Airlines subsequently stops supplying them with any aid.

Spares for the Bluefin underwater vehicle should arrive in Australia tomorrow (reported by the Mirror), hopefully this will enable Ocean Shield to get back out searching.

Its still really early days, hopefully persistence will pay off.

but they could hold the information pertaining to the GPS position of their release surely.

Someone else is already trying to tout a film around Cannes

So far they've knocked together a trailer, that's all.

Also - engines large and heavy so sink very quickly and should give a decent target for search.

Personally I think those saying "it will never be found" are talking bunk. But I've been wrong before....

My prediction. It will be found, or it won't. Sorted.

[Vaud]

It won't be found in a timeframe that will inform us of anything useful, other than it crashed.

Unexplained loss of all cabin pressure and anoxia seem to be the most probable causes to me.

Really? Even after all this time and "evidence" you really think that?

[Vipers]

Then again could have crashed in dense unpopulated jungle and may not be discovered for eons of time.

I don't think they know for certainly where it is supposed to have crashed, two sites mentioned, off Oz and one East of Malaya arnt exactly close are thet?.

I can't see the actual film being much longer tbh.

Doesn't explain the switching off both the transponder and CPDLC though.

Wasnt it stated that it had been concluded using the data available that they had expertly flown around the radar borders to avoid detection and then been lost.... to me that blew the hypoxia theories out of the water.
