On September 11, 2001, a series of coordinated terrorist attacks were carried out by the extremist group al-Qaeda against the United States. Four commercial airplanes were hijacked; two were flown into the Twin Towers of the World Trade Center in New York City, causing their collapse, while a third struck the Pentagon in Arlington, Virginia. The fourth plane, United Airlines Flight 93, crashed in Pennsylvania after passengers attempted to overcome the hijackers. The attacks resulted in nearly 3,000 deaths and led to significant changes in U.S. domestic and foreign policy, including the War on Terror and increased security measures.
