9/11 hijacker Hani Hanjour practices on a Boeing 737-200 simulator for a total of 21 hours at the JetTech International flight school in Phoenix, Arizona. Hanjour also attends ground school and pays just under $7,500 for the training. Despite only completing 21 of his originally scheduled 34 hours of simulator training, according to the FBI this is the best-trained of the four hijacker pilots (see Spring-Summer 2001). However, an instructor comments: “Student made numerous errors during performance… including a lack of understanding of some basic concepts… Some of the concepts involved in large jet systems cannot be fully comprehended by someone with only small prop plane experience.” [US District Court for the Eastern District of Virginia; Alexandria Division, 7/31/2006 ] The school contacts the FAA to warn it of Hanjour’s poor English and flying skills (see January-February 2001).
