Forever to be known as simply 911
The worst terrorist attack in U.S. history occurred as four large passenger jets were hijacked then crashed, killing nearly 3,000 persons. Four separate teams of Mideast terrorists, operating from inside the U.S., boarded the morning flights posing as passengers, then forcibly commandeered the aircraft. Two fully-fueled jumbo jets, American Airlines Flight 11 carrying 92 people and United Airlines Flight 175 carrying 65 people, had departed Boston for Los Angeles. Both jets were diverted by the hijackers to New York City where they were piloted into the twin towers of the World Trade Center. The impact and subsequent fire caused both 110-story towers to collapse, killing 2,752 persons including hundreds of rescue workers and people employed in the towers. In addition, United Airlines Flight 93, which had departed Newark for San Francisco, and American Airlines Flight 77, which had departed Dulles (Virginia) for Los Angeles, were hijacked. Flight 77 with 64 people on board was diverted to Washington, D.C., then piloted into the Pentagon building, killing everyone on board and 125 military personnel inside the building. Flight 93 with 44 people on board was also diverted toward Washington but crashed into a field in Pennsylvania after passengers attempted to overpower the terrorists on board.
Patriot Day is an annual observance on September 11 to remember those who were injured or died during the terrorist attacks in the United States on September 11, 2001. Many Americans refer Patriot Day as 9/11 or September 11.
