Drop tower

A drop tower is a type of amusement park ride incorporating a central tower structure with one or more gondolas attached. In a typical modern configuration, each gondola carrying riders is lifted to the top of the tower and then released to free fall back down to ground level. This produces a feeling of weightlessness followed by rapid deceleration. A magnetic braking system, or a variation that relies on pistons and air pressure, is used to safely bring the gondola to a complete stop. One of the earliest drop towers configured as an amusement ride was a parachute ride that debuted at the 1939 New York World's Fair, which was inspired by paratrooper training devices used by the Soviet Union in the 1920s.
