On a clear Tuesday morning, four airliners were taken. Two were flown into the towers of the World Trade Center in New York, one into the western face of the Pentagon, and one came down in a field near Shanksville, Pennsylvania, after the passengers and crew went forward at the cockpit door.

Two thousand nine hundred and seventy-seven people were killed. Three hundred and forty-three were firefighters of the New York City Fire Department. Seventy-one were law enforcement officers. Eight were paramedics and emergency medical technicians. One hundred and twenty-five died at the Pentagon, military and civilian together. The rest - some two thousand four hundred of them - had gone to work, or boarded a plane, and belonged to no service at all.

None of them began that morning as heroes. A great many of them ended it as heroes: men and women who carried strangers down stairwells, who stayed with people who could not walk, who held a door, who went back up. Four men on a flight over Pennsylvania, who had thirty minutes of telephone calls and knew what had already happened, decided where their aircraft would come down.

At Arlington, the nation set aside its own rules of eligibility and buried the Pentagon's civilian dead in national ground. It had decided that on this day the distinction did not apply.
