Take a look at Bloxin's very first post here. # 2370 He may be on to something.
I know the O2 bottle stuff has been discussed, but follow this.
The O2 bottle lets go, and renders transponders and comms inop. Maybe started a decompression.
The captain starts an a/p descent an hits the nearest TRN waypoint, which was shown by Tarzanboy, to be on the north end of Malaysia.
The plane turns, descends some, and tracks to TRN, then westward. The crew passes out due to no O2.
Maybe pax, cabin crew as well? Don't know where their O2 is located, or could be damaged by the original problem.
Just another set of ideas.
