Future 9/11 hijacker Waleed Alshehri books a one-way airplane ticket from San Francisco to Miami, via Las Vegas, at a Florida travel agent office. According to an FBI report about the 9/11 attacks, he is accompanied by an older man in his mid-40s. Days after 9/11, the travel agent who books the flight will be shown photographs of the other hijackers in an attempt to determine who this other man is, but the agent will not recognize any of the hijackers as that man. Apparently, Alshehri does not use the flight, although he does fly from Miami to San Francisco and back a few days later. [Federal Bureau of Investigation, 4/19/2002] Mohamed Atta is believed to be the oldest of the 9/11 hijackers, and is 33 years old by the time of 9/11.
