Here's what we know: Foul play was involved. Demands were not made. The flight was not being directed to a terrorist haven. The plane was intentionally lost/sunk by someone who wanted the world to think he was dead. One passenger will never be found amoung the wrekage- probably parachuted out of the plane.
