Mohamed Atta was an Egyptian terrorist hijacker for al-Qaeda. Ideologically a pan-Islamist, he was the ringleader of the September 11 attacks and served as the hijacker-pilot of American Airlines Flight 11, which he crashed into the North Tower of the original World Trade Center as part of the coordinated suicide attacks. Aged 33, he was the oldest of the 19 hijackers who took part in the mission. Before the attacks, he worked as a construction engineer.
