8:42: Flight 93, a Boeing 757, takes off with 37 passengers and seven crew members from Newark International Airport, bound for San Francisco International Airport, following a 40-minute delay due to congested runways. Four hijackers are aboard. Its flight path initially takes it close to the World Trade Center, which is 4 minutes away from being struck, before moving away westwards.

8:46:40:[13] Flight 11 crashes at roughly 466 mph (790 km/h or 219 m/s or 425 knots) into the north face of the North Tower (1 WTC) of the World Trade Center, between floors 93 and 99. The aircraft enters the tower intact. It plows to the building's 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, but no one above the impact zone is able to do so.
