While Flight 93's passengers organized their revolt, a breakdown was unfolding inside the White House and the military.

Passengers stormed the cockpit and fought hijackers for control of United Airlines Flight 93 before it crashed in a field near Shanksville, Pennsylvania, at 10:03 a.m. Sept. 11, 2001. In Washington that morning, a shootdown order that the vice president believed had reached the military never made it to a single fighter pilot in time to matter.

The Shootdown Order That Never Arrived

While Flight 93's passengers organized their revolt in the plane's final minutes, a breakdown was unfolding inside the White House and the military's air defense network, one that the 9/11 Commission would later document in detail: 8:46 a.m. and 9:03 a.m.: Airliners crashed into the World Trade Center towers. 10:03 a.m.: Flight 93 crashed in Pennsylvania. Roughly 10:18 to 10:20 a.m.: Vice President Dick Cheney confirmed a presidential authorization by phone with President George W. Bush, allowing military fighter pilots to shoot down any hijacked commercial airliner that failed to respond to instructions. 10:31 a.m.: Cheney's order reached the military's chain of command, the Northeast Air Defense Sector, (NEADS).
