According to the Final Report of the official Commission of Inquiry, the pilot of AA77 was Hani Hanjour (p. 225), not Nawaf Alhazmi.
Hani Hanjour was described in a Newday article of 23 September 2001 as an incompetent pilot:
When Baxter and fellow [flight] instructor Ben Conner took the slender, soft-spoken Hanjour on three test runs during the second week of August , they found he had trouble controlling and landing the single-engine Cessna 172. Even though Hanjour showed a federal pilot’s license and a log book cataloging 600 hours of flying experience, chief flight instructor Marcel Bernard declined to rent him a plane without more lessons.
Alleged 9/11 hijacker, Nawaf Alhazmi, is reported to be the pilot of Flight 77 in an AP article.
“The terrorist believed to have flown a hijacked airliner into the Pentagon on Sept. 11, 2001, obtained a California driver’s license without providing the required Social Security number for identification, officials are acknowledging for the first time. Nawaf M.S. Alhazmi then used that license when he registered for the flight training that enabled him to pilot the doomed airliner.” – San Luis Obispo Tribune/AP (02/06/05)
