“9/11” redirects here. For the date September 11.
The September 11 attacks (also referred to as 9/11) were a series of four coordinated terrorist attacks by the Islamic Terrorist group al-Qaeda. This attack will always be remembered as one of the historical attacks.
Two of the planes were flown into the twin towers of the World Trade Center in New York City, a third plane hit the Pentagon just outside Washington, D.C., and the fourth plane crashed in a field in Pennsylvania.
On September 11, 2001, at 8:45 a.m. on a clear Tuesday morning, an American Airlines Boeing 767 loaded with 20,000 gallons of jet fuel crashed into the north tower of the World Trade Center in New York city. The impact left a gaping, burning hole near the 80th floor of the 110-story skyscraper.
As millions watched the events unfolding in New York, American Airlines Flight 77 circled over downtown Washington D.C., before crashing into the west side of the Pentagon military headquarters at 9:45 a.m.
At 10:30 a.m., the north building of the twin towers collapsed. Only six people in the World Trade Center towers at the time of their collapse survived.
Meanwhile, a fourth California-bound plane—United Flight 93—was hijacked about 40 minutes after leaving Newark Liberty International Airport in New Jersey.
Did you know? September 11, 2001, was the deadliest day in history for New York City firefighters: 343 were killed.
Some of the terrorists had lived in the United States for more than a year and had taken flying lessons at American commercial flight schools. Others had slipped into the country in the months before September 11 and acted as the “muscle” in the operation.
The 19 terrorists easily smuggled box-cutters and knives through security at three East Coast airports and boarded four early-morning flights bound for California, chosen because the planes were loaded with fuel for the long transcontinental journey. Soon after takeoff, the terrorists commandeered the four planes and took the controls, transforming ordinary passenger jets into guided missiles.
