Little or no evidence there? You mean 95% of the plane isn't enough? Identifying ALL of the passengers AND the hijackers isn't enough? Should they have come up with more people than were on the plane maybe? I geuss the witnesses who saw it doesn't count? I guess the responders who were there and saw it don't count? I guess the RADAR data, the FDR, the voice recorder aren't enough? The confessions, the money trails, the phone calls aren't enough? There isn't a single more conclusive plane crash in history than flight 93.
And if that's not enough, go look up flight 1771. Almost identical to the crash of flight 93. And guess what. The witnesses were all claiming how there was almost nothing left of the plane.
