Between January and October 1999: Hamburg Cell Downloads Flight Training Software

According to German investigations, by at least this time, the al-Qaeda Hamburg cell including Mohamed Atta, Marwan Alshehhi, Ziad Jarrah, and Ramzi bin al-Shibh has come up with the idea of attacking the US using airplanes. This theory is based on witness statements and the discovery by the German police of a flight simulator file on a computer used by the Hamburg cell that was downloaded between January and October 1999. [Washington Post, 9/11/2002; Burke, 2004, pp. 244] Both Atta and Alshehhi start taking lessons on ultralight aircraft this year (see April 1999, October 1999, and December 1999). Some suggest they first joined the 9/11 plot in early 1999 (see Early 1999). However, the 9/11 Commission claims that the 9/11 plot was hatched by al-Qaeda’s leadership and was communicated to the Hamburg al-Qaeda cell in Afghanistan in December 1999. [9/11 Commission, 7/24/2004, pp. 165-169]
