these are two pictures of what the Gov't has used to prove the hijacker:
his name is Hanjour...
first picture is an atm 9/5/01.. second is "airport on 9/11/01" (some say the video isn't from that date)
look at the difference b/w his hairline, and the shape of his head
[this was at dulles airport, and well you guys know Marvin Bush was in charge of security in this airport]
