2. Wing falls off.
3. Departing wing shears off the tail.
Just one problem. Both wings were found not far from the fuselage and engines. The tail was apparently the first part of the plane to fall off, since it detached while the plane was still over water. The close distance of the other components to each other indicates an almost simultaneous disintegration.
Not to mention that the undamaged tail shows no indication whatever of a blow severe enough to knock it off.
I have no idea what the cause of this crash was, but the physical evidence tends to indicate the eyewitness was mistaken about the sequence of events. Who are you going to believe, him or your own eyes?
Now if we're going to get into conspiracy theories about coverups about where the wings were found, then it's time to get out the foil.
