Hijackers crash Flight 175 into floors 77 to 85 of the World Trade Center's South Tower, killing everyone on the plane and hundreds inside the building. During its final nose dive, the plane lost altitude at a rate of approximately 5,000 feet per minute.1

The impact severs two of three emergency stairwells and 80% of the elevator cables, trapping many inside elevator cars and cutting off escape routes. Despite rubble choking it, Stairwell A remains passable. Eighteen successfully evacuate down it from above the impact zone.
