Collapse of the World Trade Center

The original World Trade Center in Lower Manhattan, New York City was destroyed during the terrorist attacks of September 11, 2001, after being struck by two hijacked commercial airliners. One World Trade Center was hit at 8:46 a.m. Eastern time and collapsed at 10:28 a.m. Two World Trade Center was hit at 9:03 a.m. and collapsed at 9:59 a.m. The resulting debris severely damaged or destroyed more than a dozen other adjacent and nearby structures, ultimately leading to the collapse of 7 World Trade Center at 5:21 p.m.

A total of 2,763 people were killed in the crashes, fires, and subsequent collapses, including 2,192 civilians, 343 firefighters, and 71 law enforcement officers as well as all the passengers and crew on the airplanes, which included 147 civilians and the ten hijackers.
