What floor was hit in 9 11?

8:46 a.m. - Flight 11 crashes into floors 93 through 99 of the North Tower.



During the attacks on September 11, 2001, two hijacked aircraft struck the Twin Towers of the World Trade Center at different levels. American Airlines Flight 11 struck the North Tower (1 WTC) between the 93rd and 99th floors at 8:46 AM, instantly severing all three emergency stairwells and trapping everyone on the floors above. Seventeen minutes later, at 9:03 AM, United Airlines Flight 175 struck the South Tower (2 WTC) between the 77th and 85th floors. Notably, because the South Tower was hit at an angle, one stairwell (Stairwell A) remained briefly passable, allowing a small number of people from the impact zone and above to escape before the building collapsed. The impact zones were essentially at the "upper third" of both buildings, which stood 110 stories tall. These specific floors were chosen by the hijackers to maximize structural damage while ensuring the planes were flying high enough to avoid surrounding obstacles in the lower Manhattan skyline.
