Hani Salih Hasan Hanjour was a Saudi Arabian terrorist who was the hijacker-pilot of American Airlines Flight 77, crashing the plane into the Pentagon as part of the 9/11 attacks in 2001.

The hijackers in the September 11 attacks were 19 men affiliated with Islamist jihadist organization al-Qaeda. They hailed from four countries; 15 of them were citizens of Saudi Arabia, two were from the United Arab Emirates, one was from Egypt, and one from Lebanon. To carry out the attacks, the hijackers were organized into four teams each led by a pilot-trained hijacker who would commandeer the flight with three or four "muscle hijackers" who were trained to help subdue the pilots, passengers, and crew. Each team was assigned to a different flight and given a unique target to crash their respective planes into. Mohamed Atta was the assigned ringleader over all 4 groups.
