8:46:30: Flight 11 crashes at roughly 466 mph (790km/h or 219m/s or 425 knots) into the north face of the North Tower (1 WTC) of the World Trade Center, between floors 93 and 99. (Many early accounts gave times between 8:45 and 8:50). The aircraft enters the tower mostly intact. It plows to the building core, severing all three gypsum-encased stairwells, dragging combustibles with it. A powerful shock wave travels down to the ground and up again. The combustibles and the remnants of the aircraft are ignited by the burning fuel. People below the severed stairwells start to evacuate no one above the impact zone is able to do so.

9:03:02: Flight 175 crashes at about 590 mph (950 km/h) into the south face of the South Tower (2 WTC) of the World Trade Center, banked between floors 77 and 85

9:37:46: Flight 77 crashes into the western side of the Pentagon and starts a violent fire. The section of the Pentagon hit consists mainly of newly renovated, unoccupied offices. All 64 people on board are killed, as are 125 Pentagon personnel.

10:03:11: United Airlines Flight 93 is crashed by its hijackers and passengers, due to fighting in the cockpit 80 miles (129 km) southeast of Pittsburgh in Somerset County, Pennsylvania. Later reports indicate that passengers had learned about the World Trade Center and Pentagon crashes on cell phones and at least three were planning on resisting the hijackers; the resistance was confirmed by Flight 93's cockpit voice recording, on which the hijackers are heard making their decision to down the plane before the passengers succeed in breaching the cockpit door.
