The survivor's staircase is a special staircase that saved many lives during the 9/11 terrorist attack in New York City. Normally, when people are in a high-rise building and there is an emergency, they use elevators to get down quickly. But during the 9/11 attack, the elevators were not working due to the damage caused by the planes crashing into the building.
Therefore, many people had to use the stairs to get out of the building. The survivor's staircase was the last intact staircase that was used by many people to escape the building before it collapsed. The staircase was originally located in the North Tower of the World Trade Center and was one of the few ways out for people who were on higher floors.
The staircase was made of concrete and had steel reinforcing rods inside it to make it strong and sturdy. It was located near the center of the building, so it was easier for people to get to it.
During the attack, many people used the staircase to get out of the building. They had to walk down hundreds of steps to reach safety on the ground floor. Some people were injured or exhausted, and others were helping those who were struggling.
Thanks to the survivor's staircase, many people were able to escape the World Trade Center before it collapsed. It became a symbol of hope for the survivors and a reminder of the tragedy that occurred on that day. Today, the staircase is part of the 9/11 Memorial Museum and is a tribute to those who lost their lives and those who survived.
