World Trade Center site
On the morning of September 11, 2001, Islamic terrorists affiliated with Al-Qaeda hijacked American Airlines Flight 11 and United Airlines Flight 175, both which were en route to Los Angeles, and intentionally crashed them into the two main towers of the World Trade Center. The towers collapsed within two hours of the collisions. 2,606 people, including 2,192 civilians, 71 law enforcement officers, and 343 firefighters, who were in the towers and in the surrounding area died in the attacks, as well as 147 civilians and the 10 hijackers aboard the two airliners. After the collapse of the World Trade Center, hospital workers and law enforcement officers began referring to the World Trade Center site as "Ground Zero".
History of New York City (1978–present)
On September 11, 2001, Islamic terrorist hijackers linked to the jihadist organization Al-Qaeda piloted two hijacked passenger airliners into each of the twin 110 story World Trade Center towers. The airplanes, designated for transcontinental flights and therefore fully loaded with jet fuel, were hijacked mid-flight and intentionally crashed into the towers in the early morning hours of September 11. The crashes caused massive structural damage during impact, ripping gaping holes into the towers, and ignited raging fires, that caused both weakened towers to collapse in less than two hours. Together with a simultaneous attack on the Pentagon in Arlington, Virginia, and a failed plane hijacking that resulted in a plane crash in Shanksville, Pennsylvania, 2,977 victims died in the attacks.
