"and what hit the pentagon"

FYI - that picture w/ the taxi...
that taxi driver's statement is what a lot of conspiracy theorists use as "proof" He made the statement that he did not see the plane hit. The reason (and next part of the statement, conveniently left off by the conspiracy nuts) is that the reason he didn't see it was because a piece of the plane (or light?) hit and smashed his windshield. (as you can see in the picture)
This is also very good
