Six weeks later, these same passengers carried out the attacks of September 11, 2001.

Woods observed these four men, of apparent Middle Eastern origin, behaving so strangely that he reported them to flight attendants and authorities when he landed. They didn't touch food or drink, they didn't read, they didn't sleep, they didn't make themselves comfortable. They sat stiffly in their seats and stared straight ahead, saying nothing to the flight attendants and speaking only to each other in inaudible tones.

Basically, that was the test flight for the 9/11 terrorist attacks, in which 19 terrorists hijacked 4 scheduled flights, and among these there was one of the same route as the plane that Woods took.
