Agents from Oklahoma City FBI office visit the Airman Flight School in Norman, Oklahoma to investigate Ihab Ali Nawawi, who has been identified as bin Laden’s former personal pilot in a recent trial. The agents learned that Nawawi received his commercial pilot’s license at the school 1993, then traveled to another school in Oklahoma City to qualify for a rating to fly small business aircraft. He is later named as an unindicted coconspirator in the 1998 US Embassy bombing in Kenya. The trial witness who gave this information, Essam al Ridi, also attended flight school in the US, then bought a plane and flew it to Afghanistan for bin Laden to use (see Early 1993). [Boston Globe, 9/18/2001; CNN, 10/16/2001; Washington Post, 5/19/2002; US Congress, 10/17/2002] When Nawawi was arrested in May 1999, he was working as a taxi driver in Orlando, Florida (see May 18, 1999). Investigators discover recent ties between him and high-ranking al-Qaeda leaders, and suspect he was a “sleeper” agent. [St. Petersburg Times, 10/28/2001] However, the FBI agent visiting the school is not given most background details about him. [US Congress, 7/24/2003] It is not known if these investigators are aware of a terrorist flight school warning given by the Oklahoma City FBI office in 1998. Hijackers Mohamed Atta and Marwan Alshehhi later visit the Airman school in July 2000 but ultimately will decide to train in Florida instead. [Boston Globe, 9/18/2001] Al-Qaeda agent Zacarias Moussaoui will take flight lessons at Airman in February 2001 (see February 23-June 2001). One of the FBI agents sent to visit the school at this time visits it again in August 2001 asking about Moussaoui, but he will fail to make a connection between the two visits (see August 23, 2001).
