Almost wonder if the Aussies had some idea of where to look from their OTHR setup:

Looks like it is far further south than that. Nearly in the Southern Ocean

WTF! This just brings up more questions... debris wouldn't have drifted this far South right?

Yes - I was wondering though if the Aussie OTHR may have picked it up on it's way there - it could have been in range of their WA station.

joker97: yeah so much junk has come up since, I can't even remember which bit is fact and which aren't ...

all I know now is - it took off, it disappeared, no one's found anything. maybe i'll go back to the wiki page ...

Yeah, I think you got all the facts there... all the rest is pretty much supposition and speculation.

The debris hasn't drifted that far south, it flew that far south. That's the area where MH370 flew to before it ran out of fuel.

I still stand by my original theory, there was a major problem with the aircraft which took out the pilots O2 system and depressurised the aircraft. The pilots had time to don their O2 masks and turn the aircraft towards the best airfield for an emergency landing. Within 30 to 40 seconds they were unconscious with no time for a mayday call.

The problem what ever it was caused the communication systems to gradually fail. The aircraft continued flying on auto pilot heading in a southwesterly direcction till it ran out of fuel.

Hard to believe it was so major as to have killed everyone on board, but not major enough to cause the plane to go into the ocean MUCH sooner. Also hard to believe that with that occuring the pilot had time to plot that complicated stuff into the computer and have the plane turned toward.... nothing of significance.

Here is a very good read on the "Tire fire" theory, also busts open the depressurization theory also for much the same reasons.

I think one of the pilots went for a piss, and locked the other pilot out. Why he did that, we may never know.

But someone programed the FMC to change its course, if they could program the FMC they could do a call for help using the transponder (7700 code) or HF or VHF radio call.

Wow even without all that flight experience I debunked the theory of a fire of this nature on board.

I don't buy this theory at all.

The 777 has systems in place to measure cabin pressure. If the pressure goes above 10,000ft it alarms, with out hooters and alarms on control LCD's. No pilot could miss that.

They would then go through their depressurization procedures (Oxygen Masks, ATC comms and then dropping to flight levels below 10,000ft).

The cockpit oxygen has ample oxygen.

Mayday calls take seconds to do, also setting the transponder to 7700 would alert ATC that there is an issue. All part of the procedures.

A hole in the fuselage would be enough for depressurisation, it wouldn't need to be big. A fault the the O2 system and it's all over. The aircraft would still fly happily. There would be a lack of cooling air for the cooling system for the avionics which coould result in some systems gradually failing.

Using heading mode or a nearest - direct to operation isn't complicated and doesn't take long.

That blog doesn't disprove depressurisation at all. How does he know the crew acted in any particular manner?

That is one persons theory based on some assumptions, just like my theory.

To me right now crew incapacitation seems to be the most likely cause. For reason I stated before I don't believe fire to be the cause.

The problem I have with this theory is that the primary radar track shows the aircraft going West, not southwest. I buy the original turn to the west, and a fire or depressurisation or whatever disabled the pilots. But then half an hour later the aircraft supposedly turned further south.

My betting is that what they're discovered in the South Indian Ocean is a container or something not related to the aircraft.

You didn't read or didn't understand my post did you? Did you not read that I postulated the failure took out the O2 system. How do the crew or passengers survive at 35,000 feet in an unpressurised aircraft without oxygen?

Because those drills and drilled into pilots over and over and over again. Its almost like a reflex. ATC Comms are a big part of that, same with transponder codes.
