I support an alternative conspiracy theory.

12. OH heavens! Imagine the temerity of actually intervewing the witnesses,

mapping their locations, and asking for confirmation of their statements, and taking into consideration what was actually in their line of sight.! E GADS!
So the plane swung a little wide in it's death-spiral, and didn't line up with the path of damage. WHAT TO DO? WHAT TO DO?
Well, there's always Operation Noble Eagle at Dover Air Base, where DNA IDs were made on 184 of 189 samples supplied; and since 125 Pentagon occupants died, the rest MUST be from the plane , right? There, that ought to settle it. Never mind the lack of proof, trail of custody, and validity of the comparison data (GIGO), once that hits the teleprompter, it's case closed. The seats and luggage and tonnage of plane parts? Just have someone claim to have seen such, no need for photos or actual debris.
And throw in a parking camera photo of smoke cropped to suggest something real.
You don't think the hijacking of the US military for the PNAC declared purpose of world domination deserves less, do you?
