On September 11, 2001, four commercial airliners were hijacked by terrorists affiliated with al-Qaeda. American Airlines Flight 11 and United Airlines Flight 175 were flown into the North and South Towers of the World Trade Center in New York City, causing both buildings to collapse. American Airlines Flight 77 crashed into the Pentagon, while United Airlines Flight 93 was headed toward a target in Washington, D.C., but passengers attempted to retake control, leading to its crash in Pennsylvania. All passengers and crew on the four planes, along with many others on the ground, lost their lives in the attacks.
