Two Saudis, Hamdan al Shalawi and Mohammed al-Qudhaeein, are detained for trying twice to get into the cockpit on a passenger airplane flying from Phoenix, Arizona, to Washington, D.C. They claim they thought the cockpit was the bathroom, and sue the FBI for racism. After 9/11, the FBI will consider the possibility that this was a “dry run” for the 9/11 attacks, but apparently does not come to a definite conclusion. In late 1999, it is discovered that the two were traveling to Washington to attend a party at the Saudi embassy and their ticket had been paid by the Saudi government. Apparently influenced by their government ties, the FBI decides not to prosecute or investigate the men. Al-Qudhaeein leaves the US. In 2000, intelligence information will be received indicating al-Qudhaeein had received explosives and car bomb training in Afghanistan. As a result, his name is added to a no-fly watch list. In April 2000, FBI agent Ken Williams is investigating Zacaria Soubra, a suspected radical militant attending a flight school in Phoenix, and discovers that the car Soubra is driving is actually owned by al-Qudhaeein. Soubra is friends with al Shalawi and al-Qudhaeein. This and other evidence will influence Williams to write his later-famous July 2001 memo warning about potential terrorists training in Arizona flight schools (see July 10, 2001). In August 2001, al-Qudhaeein applies for a visa to reenter the US, but is denied entry. It has not been revealed why al-Qudhaeein wanted to reenter the US, or if Williams or anyone else in US intelligence knew about his attempted reentry, or if anyone took action as a result of it.

In November 2000, US intelligence discovers he is training in a camp in Afghanistan, learning how to conduct a car bomb attack. One of his friends in Arizona is Ghassan al Sharbi, an al-Qaeda operative who will be captured in Pakistan with al-Qaeda leader Abu Zubaida. Al Sharbi is one of the targets of Williams’ July 2001 memo. [9/11 Commission, 7/24/2004, pp. 521]
