The victims of September 11
At the World Trade Center (WTC) in lower Manhattan, 2,753 people were killed when hijacked flights, American Airlines '11 and United Airlines' 175, were intentionally crashed into the north and south towers, or died as a result of the bombings. .
Of those who perished during the initial attacks and subsequent tower collapses, 343 were New York firefighters, 23 were city police officers and 37 were Port Authority agents.
The victims ranged in age from two to 85 years.
Approximately 75-80% of the victims were men.
At the Pentagon in Washington, 184 people were killed when American Airlines Flight 77, which had been hijacked, crashed into the building.
Near Shanksville, Pennsylvania, 40 passengers and crew members aboard United Airlines Flight 93 were killed when the plane crashed into a field.
The hijackers are believed to have crashed the plane at that location, rather than their unknown target, after passengers and crew attempted to retake control of the flight deck.
As of July 2019, 1,644 (60%) of 2,753 remains of WTC victims have been identified, according to the medical examiner's office.
