The morning minute by minute

Tuesday, September 11, 2001, dawned temperate and nearly cloudless in the eastern United States. — The 9/11 Commission Report, chapter 1

Nineteen hijackers seized four airliners that morning. Two struck the towers of the World Trade Center in New York, one the Pentagon outside Washington, and the fourth came down in a field near Shanksville, Pennsylvania, after its passengers fought back. This timeline follows the morning from the first takeoff at 7:59 to the fall of the North Tower at 10:28, mostly in the minutes and seconds the 9/11 Commission reconstructed from radar, radio and cockpit recordings and the calls made from the planes.

By the numbers

  • 2,977 people killed, not counting the 19 hijackers, according to the National September 11 Memorial & Museum

  • 2,753 of them in New York, 184 at the Pentagon and 40 aboard United 93, by the same count

  • 343 New York City firefighters among the dead

Reading it

Four bands run side by side, one per flight from takeoff to impact, and two more for the time each tower stood burning. Events inside a flight's band happened on board or to that aircraft. Filter by hijackings for the four flights, air traffic control for the FAA controllers who saw it unfold, air defense for NORAD's fighters, command for the President and Vice President, and evacuation and firefighting for the towers.

All times are UTC. The East Coast kept Eastern Daylight Time, four hours behind, so the first impact at 8:46:40 on the Commission's clock shows as 12:46:40 here; the notes give the local time. Flight times follow the 9/11 Commission Report (2004); the collapse times follow NIST's investigation (2005), whose impact times differ from the Commission's by a few seconds.
