9/11 was the single largest loss of life from a foreign attack on American soil.
The rescue and recovery clean-up of the 1.8 million tons of wreckage from the World Trade Center site took 9 months.
Passengers aboard United Flight 93, heard about the previous airplane attacks and attempted to retake control of the plane from hijackers. As a result, the hijackers deliberately crashed the plane in a Pennsylvania field instead of at their unknown target.
