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.
Swiss manufacturer Intamin renewed interest decades later when it pioneered the modern drop tower with an early iteration released in the 1980s, which was later refined to use magnetic braking systems in the 1990s. This led to larger models, such as the Giant Drop and Gyro Drop. S&S Sansei modified the concept and released their own variation that employs pneumatics, which involves pistons, air pressure, and steel cables to control the speed of the gondola at all times. This variation can move the gondola at speeds faster than free fall and can alternatively be configured to accelerate gondolas in the opposite direction, moving at fast speeds up the tower as well as down.
Drop towers can vary in height and capacity, and some models are either mass-produced or custom. Newer features include gondolas that rotate along the vertical plane, tilting riders so they are facing the ground prior to the gondola's release. Falcon's Fury at Busch Gardens Tampa Bay, for example, is a 335-foot (102 m) tower that rotates riders to face the ground, and then returns riders to an upright position as the gondola nears the end of the drop.
