Today marks the 8th anniversary of terrorist attacks that happened in New York on the World Trade Center's "Twin Towers".
19 high jackers took control of four commercial airliners en route to San Francisco and Los Angeles from Boston, Newark, and Washington D.C.
Three buildings in the World Trade Center Complex collapsed due to structural failure on the day of the attack. The south tower (2 WTC) fell at approximately 9:59 a.m., after burning for 56 minutes in a fire caused by the impact of United Airlines Flight 175. The north tower (1 WTC) collapsed at 10:28 a.m., after burning for approximately 102 minutes.
An estimated that about 17,400 civilians were in the World Trade Center complex at the time of the attacks, while turnstile counts from the Port Authority suggest that 14,154 people were typically in the Twin Towers by 8:45 a.m.
At least 200 people jumped to their deaths from the burning towers landing on the streets and rooftops of adjacent buildings hundreds of feet below.
There were a total of 2,993 deaths, including the 19 hijackers: 246 on the four planes (from which there were no survivors).
The vast majority of people below the impact zone safely evacuated the buildings, along with 18 people who were in the impact zone in the south tower. 1,366 people died who were at or above the floors of impact in the North Tower. According to the Commission Report, hundreds were killed instantly by the impact, while the rest were trapped and died after the tower collapsed. As many as 600 people were killed instantly or were trapped at or above the floors of impact in the South Tower.
A total of 411 emergency workers who responded to the scene died as they attempted to rescue people and fight fires
All of the deaths in the attacks were civilians except for 55 military personnel killed at the Pentagon.
2,993 people, including the hijackers, died in the attacks.
