On the morning of September 11, 2001, al-Qaeda terrorists hijack four commercial U.S. airliners that are departing from East Coast airports. The terrorists fly two jet airliners into the World Trade Center's Twin Towers in New York City and a third aircraft into the Pentagon in Arlington, Virginia. A fourth aircraft, United Airlines Flight 93, crashes into an open field near rural Shanksville, Pennsylvania, killing all on board. The four aircraft strikes kill nearly 3,000 people, the deadliest attack on American soil by any foreign nation or terrorist group.
Aboard Flight 93
Alerted to the events at the World Trade Center and the Pentagon, the forty unarmed passengers and crew of Flight 93 take quick and determined action. Their revolt prevents Flight 93 from reaching the terrorists' intended target.
Evidence later reveals that the target is most likely the U.S. Capitol, where the Senate and House of Representatives are in session. Flight 93 crashes less than 20 minutes flying-time from Washington, D.C.
