One U.S. Theory: Plane's Disappearance 'Act of Piracy'

[EX500rider]

30. I am fine with the "accident" theory till I get to the part about multiple course changes..

...some which appeared to be waypoints not on the way to the original destination..and the cascading failure of comm equip makes it look like it was shut off maybe, although a fire could have done that also, I just can't imagine a flight crew not calling in a MAYDAY after smelling smoke and diverting to closest airport. Radio, sat phone, cell phones, etc, none worked from the get go? And if they all were unconscious I have issues with the subsequent course changes, unlikely they had time to plot in some weird course while fighting a fire on board...seems like slapping on the auto pilot might be the most you would do..

On the hi-jacking/piracy side it does seem easier to buy a older jet sitting out in the desert somewhere then do this though if the plan is to use the plane later. Maybe the passengers rallyed at some point and tried to retake the cockpit and the pilot put her into the drink instead..

I lean towards the hypoxia theory but they all seem to have some holes in them.
