At approximately 8:46 a.m. on a clear Tuesday morning, an American Airlines Boeing 767 loaded with 20,000 gallons of jet fuel crashes into the north tower of the World Trade Center in New York City. The impact left a gaping, burning hole near the 80th floor of the 110-story skyscraper, instantly killing hundreds of people and trapping hundreds more in higher floors.

As the evacuation of the tower and its twin got underway, television cameras broadcasted live images of what initially appeared to be a freak accident. Then, 17 minutes after the first plane hit, a second Boeing 767—United Airlines Flight 175—appeared out of the sky, turned sharply toward the World Trade Center, and sliced into the south tower at about the 60th floor. The collision caused a massive explosion that showered burning debris over surrounding buildings and the streets below. America was under attack.

As millions watched in horror the events unfolding in New York, American Airlines Flight 77 circled over downtown Washington, D.C. and slammed into the west side of the Pentagon military headquarters at 9:37 a.m. Jet fuel from the Boeing 757 caused a devastating inferno that led to a structural collapse of a portion of the giant concrete building. All told, 125 military personnel and civilians were killed in the Pentagon along with all 64 people aboard the airliner.
