This is possibly the best theory I've read so far.

Payne Stewart Syndrome? I doubt it.

“This would be quite similar to what happened with Helios Flight 522 on 29th December 1997 14 August 2005 when flight crew failed to react to pressure warnings.”

Is this sentence accurate?

Depending on the level of corrosion, there would have been a gradual depressurization of of the cabin pressure as oxygen was sucked out of the aircraft. The gradual decompression would have not been noticed by the crew ...

The 777 has a rather robust and prominent alert to the pilot of "high cabin altitude".

Hypoxia would not account for the end of transmissions of the ADS-B, ADS-C and ACARS data. To disable these transmitters would require either consciously removing power to them (pulling the circuit breakers) or a catastrophic destruction of the aircraft at altitude. Since there is no floating debris anywhere near the point of last data transmitted then we have to fall back on choice #2: intentional disabling.

This is not the first time a pilot has planned a suicide for insurance and it may have happened here. The pilot has to disable the data transmissions and steer the aircraft to a point on the planet where it will not be found and recovered and the cockpit voice recorder recovered.

But it's all speculation at this point.

Da Plane!!! Da Plane!!! Where’s Da Plane???

Opinions are like...

Besides the trail of EM signatures the plane would have left flying through the sky for so long, even with everyone unconscious or dead, satellites would have visually picked up that long of a flight by now, at the very least.

[Boogieman]

Obviously, there must have been someone on the plane that saw Barack Obama’s birth certificate. So, they sabotaged the flight, and while the survivors were in the water, the teleporting frogmen assassins injected that person with an untraceable heart attack inducing toxin.

Don’t know, but I would very much like to know why the photo of the supposed suspects was photo shopped.

Something stinks to High Heaven here.
