world trade center attack

The September 11 attacks (often referred to as September 11, September 11th or 9/11[nb 1], in combination with the attacks' side effects on that day) were a series of four coordinated suicide attacks by al-Qaeda upon the United States on Tuesday, September 11, 2001. On that morning, 19 al-Qaeda terrorists hijacked four commercial passenger jet airliners. The hijackers intentionally crashed two of the airliners into the Twin Towers of the World Trade Center in New York City, killing everyone on board and thousands of those working in the buildings. Both towers collapsed within two hours, destroying nearby buildings and damaging others. A third airliner was crashed into the Pentagon. Hijackers had redirected the fourth plane toward Washington, D.C., targeting either the Capitol Building or the White House, but crashed it in a field near Shanksville in rural Pennsylvania after passengers attempted to retake control of the airliner. There were no survivors from any of the flights.
