Osama bin Laden. The attacks involved hijacking commercial airplanes and crashing them into buildings; al-Omari would hijack
American Airlines Flight 11, which would crash into the
World Trade Center in New York City. At the time of the hijacking, al-Omari was 22. In the autumn of 2001, after the attacks,
Al Jazeera television broadcast a tape they claim was made by him. The speaker made a farewell suicide video. In it he read, "I am writing this with my full conscience and I am writing this in expectation of the end, which is near... God praise everybody who trained and helped me, namely the leader
Sheikh Osama bin Laden." A person with al-Omari's name visited the Philippines twice in February 2001. Al-Omari and hijacker
Salem al-Hazmi entered the United States through a
Dubai flight on June 29, 2001, landing in New York City. Al-Omari had used the controversial Visa Express program to gain entry. Al-Omari likely stayed with several other hijackers in
Paterson, New Jersey (where he rented a mailbox), before moving to his own place in
Vero Beach, Florida with his wife and three children. the attacks' mastermind. The employee who gave them the IDs claimed he had no idea they were "anything more [than ordinary] customers".
