One World Trade Center [SEP] September 11 attacks
One stairwell in the South Tower, Stairwell A, somehow avoided complete destruction, unlike the rest of the building. When Flight 11 hit, all three staircases in the North Tower above the impact zone were destroyed, thus making it impossible for anyone above the impact zone to escape. 107 people below the point of impact also died.
