Only 14 people escaped from the impact zone of the South Tower after it was hit, and only four people from the floors above it. They escaped via Stairwell A, the only stairwell which had been left intact after the impact. No one was able to escape from above the impact zone in the North Tower after it was hit, as all stairwells and elevator shafts on those floors were destroyed. But a small group of people did survive the collapse in the top of the North Tower. After the collapse of the towers, only 23 survivors who were in or below the towers escaped from the debris, including 15 rescue workers. The last survivor was pulled from the rubble 27 hours after the collapse of the towers. A total of 6,294 people were reported to have been treated in area hospitals for injuries related to the 9/11 attacks in New York City. There were (excluding the hijackers) 3,001 fatalities.
