“On August 13 [2001], [potential hijacker] Zacarias Moussaoui started his new [flight] training [near Minneapolis, Minnesota]. …Two days later, the school called the local FBI office, telling agents they had what they thought was a potential hijacker on their hands. …By the next afternoon, the FBI was at the school. By nightfall, Moussaoui was in jail on immigration charges. By the following day the Minnesota agents had alerted counterterrorism officials in Washington. …One agent even wrote in the margin of his interview notes that Moussaoui was the type of guy that might hijack an airplane and fly it into the World Trade Center.”
