The Statue of Liberty has an evacuation device designed to take visitors down from the crown. The National Park Service say West Point cadet engineers created the device to take incapacitated visitors down the steep and narrow spiral staircase quickly and safely.

The 146 steps leading up to the crown were reopened to the public last July. They were closed after the Sept. 11, 2001 terrorist attacks.

The device is a folding chair that can hold up to 350 pounds.

Its speed is controlled with pulleys operated by two rescuers.
