See how the Pentagon attack on 9/11 was carried out and how it permanently altered air travel today.
On 11 September 2001, during the September 11 attacks, American Airlines Flight 77 flies off course and crashes into the Pentagon in Arlington County, Virginia, after being hijacked. All the 64 people on board the aircraft, including the 5 hijackers, are killed, along with 125 people in the building.—Enzedder
