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.

[Source: London Times]Hamburg cell members Mohamed Atta, Marwan Alshehhi, Ziad Jarrah, Ramzi bin al-Shibh, and possibly Said Bahaji travel to Afghanistan via Turkey and Karachi, Pakistan. They travel along a route often used by one of their associates, al-Qaeda recruiter Mohammed Haydar Zammar, to send potential operatives to Afghanistan for training. Turkish intelligence is aware of the route and informed German intelligence of it in 1996, leading to an investigation of Zammar (see 1996). However, it is unclear whether German or Turkish intelligence register the Hamburg cell members’ travel and how and whether they disseminate and act on this information. Jarrah is reportedly noticed by an intelligence service in the United Arab Emirates on his return journey from Afghanistan (see January 30, 2000).

Mounir El Motassadeq, an alleged member of Mohamed Atta’s Hamburg al-Qaeda cell, is convicted in Germany of accessory to murder in the 9/11 attacks. His is given the maximum sentence of 15 years. [Associated Press, 2/19/2003] El Motassadeq admitted varying degrees of contact with Atta, Marwan Alshehhi, Ramzi bin al-Shibh, Said Bahaji, Ziad Jarrah, and Zakariya Essabar; admitted he had been given power of attorney over Alshehhi’s bank account; and admitted attending an al-Qaeda training camp in Afghanistan from May to August 2000 (see May 22 to August 2000); but he claimed he had nothing to do with the 9/11 plot. [New York Times, 10/24/2002] The conviction is the first one related to 9/11, but as the Independent puts it, “there are doubts whether there will ever be a second.” This is because intelligence agencies have been reluctant to turn over evidence, or give access to requested witnesses. In El Motassadeq’s case, his lawyers tried several times unsuccessfully to obtain testimony by two of his friends, bin al-Shibh and Mohammed Haydar Zammar—a lack of evidence that will later become grounds for overturning his conviction.
