Fatalities
There were 2,974 fatalities, not including the 19 hijackers: 246 on the four planes (no one on board any of the hijacked aircraft survived),<21> 2,603 in New York City in the towers and on the ground, and 125 at the Pentagon.<22> Among the fatalities were 343 New York City Fire Department firefighters, 23 New York City Police Department officers, and 37 Port Authority Police Department officers.<23> Lieutenant General Timothy Maude was the highest ranking person killed at the Pentagon<24> and John P. O'Neill was a former assistant director of the FBI who assisted in the capture of Ramzi Yousef and was the head of security at the World Trade Center when he was killed trying to rescue people from 2 WTC.<25> An additional 24 people remain listed as missing.<26>
World Trade Center
1366 people died who were at or above the floors of impact in the North Tower (1 WTC); according to the Commission Report, hundreds were killed instantly by the impact while the rest were trapped and died after the tower collapsed.<27>
As many as 600 people were killed instantly or trapped at or above the floors of impact in the South Tower (2 WTC). Only about 18 managed to escape in time from above the impact zone and out of the South Tower before it collapsed.
At least 200 people jumped to their deaths from the burning towers (as depicted in the photograph "The Falling Man"), landing on the streets and rooftops of adjacent buildings hundreds of feet below.<28> To witnesses watching, a few of the people falling from the towers seemed to have stumbled out of broken windows.<29> Some of the occupants of each tower above its point of impact made their way upward toward the roof in hope of helicopter rescue, however; no rescue plan existed for such an eventuality, the roof access doors were locked and thick smoke and intense heat would have prevented rescue helicopters from landing.<30>
