9/11 hijacker Mohamed Atta, who is under CIA surveillance at this time, begins sending e-mails to US flight schools, inquiring about their pilot training programs. One e-mail states, “We are a small group (2-3) of young men from different Arab [sic] countries.” “Now we are living in Germany since a while for study purposes. We would like to start training for the career of airline professional pilots. In this field we haven’t yet any knowledge, but we are ready to undergo an intensive training program.” Apparently, multiple e-mails are sent from the same Hotmail account. Some e-mails are signed “M. Atta,” while others are signed “Mahmoud Ben Hamad.” [Chicago Tribune, 2/25/2003] According to the 9/11 Commission, Atta e-mails 31 different US flight schools, and requests details on the cost of training, sources of financing, and accommodation. [9/11 Commission, 7/24/2004, pp. 168] On March 23, he e-mails the Airman Flight School in Norman, Oklahoma and requests information about their flight training. One recently arrested al-Qaeda operative had trained at this school (see February 23-June 2001), and Zacarias Moussaoui will train there one year later (see February 23-June 2001).
