Radio repeaters were installed in the towers to improve communication, battery powered emergency lights were installed, and fire drills held. Individuals who evacuated for both the and attacks reportedly stated they were better prepared for the evacuations. Both story towers housed three stairwells in the central cores of each.

In the North Tower the stairs were approximately 70 ft apart, compared to the distance of ft between the stairwells in the South Tower. In the immediate aftermath of the attacks, media reports suggested that tens of thousands might have been killed. Estimates of the number of people present in the Twin Towers that morning range between 14, and 19, The National Institute of Standards and Technology determined that approximately 17, civilians were in the World Trade Center complex at the time of the attacks.
Almost all of the deaths in the Twin Towers occurred on floors trapped by the plane impacts, but it is unknown how many people were in those floors when the towers were struck. The available data suggests that between 1, [ 31 ] and 1, [ 32 ] people occupied floors 92— of the North Tower when American Airlines Flight 11 crashed into the skyscraper at , none of whom survived.

Communication breakdowns also hampered the evacuation of workers as one survivor recounted calling multiple times from the South Tower only to be put on hold twice, as operators had a lack of awareness about what was happening and were overwhelmed with the amount of calls, at times repeating incorrect information. Communication issues were also seen as first responders were utilizing different radio channels to communicate, their frequencies were overwhelmed or they had been off duty and responded without their radios.
Within moments of Flight 11's impact, the Port Authority issued a complete evacuation of the North Tower, an order that only those beneath the 92nd floor were capable of heeding. Nonetheless, the roughly 8, people who could descend were left facing a harrowing scenario. Neither tower had been designed to facilitate a mass evacuation, and each of the twins only had three stairwells descending to the ground level.
For anyone higher than the 91st floor, escape was impossible, with one victim relaying to after the first plane hit that the stairs were inaccessible for the th floor. The modeling also suggested that if Stairwell B had remained intact through the entire building all 1, projected survivors could have evacuated with an additional 2 minutes to the total time. Many people began to evacuate via the stairs on their own, while others chose to wait for instructions from the Port Authority of New York and New Jersey.
Others who chose to evacuate were also pushed into action by loved ones who had been able to contact them. Others who managed to escape credit the " Survivors Staircase ," an outdoor staircase that survived the disaster, and World Trade Center workers who knew escape routes. One survivor stated, "Between the 11th floor and the 9th floor, we wound through this maze. When we got to the plaza level we were walking through and there was one emergency light on.
There was water up to our calves. All of a sudden there was a voice. We saw someone in a miner hat. He opened the door and said 'Just keep going. Meanwhile, in the South Tower, almost all of its roughly 8, occupants knew immediately that something serious just happened in the building next door. The sound of the crashing airliner was heard by well over 4, people. Some who had glimpsed Flight 11 just before it impacted the North Tower thought it was lined up to strike their building, and the fireballs from the crash immediately thereafter were witnessed by countless employees on sides facing the North Tower.
The blast shattered windows on the South Tower's 95th floor, [ 42 ] while the tower's northern and western façades were battered by debris.
