That being said, it kills me when the tin foil hatters hew and cry that a plane would have made a bigger hole in the Pentagon if it flew into it. That's probably true, except it was, is , and has always been reported that the plane hit the ground and slid/slammed into the building.
I really don't need any convincing, but this is pure fact, if someone wants to stubbornly cling to the "missile hit Pentagon" theory.
