Oxygen percentage remains the same at 21%

The partial pressure drops which should be picked up by decompression alarm

I've been doing some research into the systems on a commercial aircraft. It seams that the communication system would have to take a direct hit in order for it not to report issues that would arise from destruction.

If there was decompression then ACARS should communicate that to the ground team. also, the engines would likely report a power/fuel related issue. We know that ACARS was working because Rolls-Royce we're getting the "Pings" to show it was online.

Another fact is that its been a week since the indecent and no reports of debris washing up on the coast or seen in the water.

Which leads me onto a Hijacking, We know that their were two passengers on that plane with false passports, and we know that it changed course (WEST) before going offline.

Question is, why would they hijack the plane?

Another question would be why do planes have transponders that can be turned off by the flight crew at all?

EG if there was one in an inaccessible place (inaccessible during flight I mean) surely that would be sensible? Just in case?

pbgben: Flight path before it dropping connection.
Notice that the next day there is a similar connection drop around the same location? Which reconnects just before making land.

Interesting that at the last minute of the recording, it changes track from 28degrees to 40degrees. Weather avoidance?

No, there is a slight course change east. If you look at recent history you can see they turn slightly.

If the transponder was faulty e.g. a short-circuit, or continuous transmission, you would want to be able to turn it off.

http://911blogger.com/news/2011-12-29/implications-september-11-flight-transponder-signal-losses has an interesting comment... "Perhaps the most significant consequence of lost September 11 flight [transponder] data to ATC was a circumstantial impression of accused hijacker flight deck takeovers."

agree there can't be any good reason in the world that a transponder should stop transmitting on a commercial airline. I would have thought there would be at least two transponders per plane.

The Malaysians deny the US media claims that the engines were run for up to 4 hours after 1.07 AM, the Malaysians state that the representatives from Boeing and Rolls Royce are working with them in Malasia and the last data sent was at 1.07
If Micke McKay, the Kiwi on the oil rig, ( who does not appear to have provided the time of his observation) saw something burning, and then extinguish itsself what could account for that?
I guess fires could "blow out" with enough speed but an engine fire alone would not knock out a transponder in the tail.

geocom:
joker97: question is - in a detonation and no debris whatsoever?

if that is possible then that's probably what it was.

if that is not possible then the everybody unconcious and the plane flew on autopilot until it ran out of fuel ... does anyone know where the autopilot would take them? presumably not onto land as someone would have seen it on their radar if it flew unresponsive to beijeng


Believe it or not this sort of thing has happened Lookup Helios Airways Flight 522
http://en.wikipedia.org/wiki/Helios_Airways_Flight_522
 




After that one, I have no idea why compulsory low oxygen alarms were not mandated for all commercial planes....


They do, if you read the wiki article you'll see that aircraft had an operative system installed, the alarm was misidentified by the crew, don't ask me how but they did.

The ones saying it flew on for up to 5 hours are US media citing "unnamed US officials".
Malaysians say it was transmitting no data to Boeing or RR and it was last heard from at 1.07.

And another page that's being constantly updated.

I'd imagine a seasoned rig worker would've seen plenty of meteorites and would know if that's what he saw.
A mate of mine in the early 90's worked on rigs and became a bit of an expert on night skies... and sliding forklifts on a wet steel deck. :D



It's certainly a mystery ATM.

Because there are times when the transponder needs to be turned off by the crew, for example sometimes when taxying.

Where was this oil rig? Jet engines "Flame Out"/"Burn Out" when they run out of fuel... so the flames he could have seen may have been it run out of fuel... or an explosion :/

look at the moment the plane could be in any corner of the galaxy. people see things all the time. at 70kms away (what the oil rig guy said) I wouldn't be able to tell venus from a satellite

You're misunderstanding the term "flame out".  In a jet engine the "Fire" or combustion is continuous unlike a piston engine which has a new fire each time the spark plug ignites the mixture in the cylinder.

When a jet (turbine) engine stops the flame goes out so to speak, hence the term flame out.  There is no burst of flame out of the exhaust area.

Ah, my mistake. That would make more sense :)
