2 Early on the morning of September 11, 2001, 19 hijackers took control of four commercial airliners en route to San Francisco or Los Angeles after takeoffs from Boston, Newark, and Washington, D.C.[4] Planes with long flights were intentionally selected for hijacking because they would be heavily fueled. The four flights involved were: American Airlines Flight 11 (from Boston to Los Angeles, crashed into the North Tower of the World Trade Center) American Airlines Flight 77 (from Washington to Los Angeles, crashed into the Pentagon) United Airlines Flight 93 (from Newark to San Francisco, crashed near Shanksville, Pennsylvania) United Airlines Flight 175 (from Boston to Los Angeles, crashed into the South Tower of the World Trade Center)

3 Along with the 110-floor Twin Towers, numerous other buildings at the World Trade Center site were destroyed or badly damaged, including WTC buildings 3 through 7 and St. Nicholas Greek Orthodox Church.The North Tower, South Tower, the Marriott Hotel (3 WTC) and 7 WTC were completely destroyed. The U.S. Customs House (6 World Trade Center), 4 World Trade Center, 5 World Trade Center, and both pedestrian bridges connecting buildings were severely damaged. The Deutsche Bank Building on 130 Liberty Street was partially damaged and demolished later. The two buildings of the World Financial Center also suffered damage.

4 There were a total of 2,996 deaths from the attacks, including the 19 hijackers and 2,977 victims.The victims included 246 on the four planes (from which there were no survivors), 2,606 in New York City in the towers and on the ground, and 125 at the Pentagon. Nearly all of the victims were civilians; 55 military personnel were among those killed at the Pentagon.

5 More than 90% of the workers and visitors who died in the towers had been at or above the points of impact. In the North Tower 1,355 people at or above the point of impact were trapped and died of smoke inhalation, fell or jumped from the tower to escape the smoke and flames, or were killed in the building's eventual collapse. A further 107 people below the point of impact did not survive. In the South Tower one stairwell remained intact, allowing 18 people to escape from above the point of impact. In the South Tower 630 people died, fewer than half the number killed in the North Tower. Casualties in the South Tower were significantly reduced by the decision of some occupants to start evacuating when the North Tower was struck.
