I'm starting to think the plane didn't make it that far.

Something catastrophic happened on board and it crashed. Simple as that. There was not time for a Mayday. (explosion or raging fire)
I really think after what's happened it could be very close to were it took off.

The people looking for this plane are chasing ghosts. Nothing yet has convinced me otherwise.

EDIT: It may not even be in the ocean.
