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.[1] 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.[1][2]

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.[2]

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.

Injuries and accidents

  • On August 22, 1999, 12-year-old Joshua Smurphat fell to his death on Drop Zone: Stunt Tower (Drop Tower) at Paramount's Great America (California's Great America) after slipping from the ride's restraints, which were still locked at the end of the ride.[3][4]
  • On June 21, 2007 (park operating as Six Flags Kentucky Kingdom), a 13-year-old girl from Louisville, Kentucky had both feet cut off above the ankle when one of the ride's cables snapped during operation.[5] Following the incident, all Intamin towers were temporarily closed and the Carowinds model was found to have stretched cables.[6]
  • On February 24, 2012, 14-year-old Gabriella Yukari Nichimura died in an accident at Hopi Hari, Vinhedo, São Paulo State, Brazil. She fell from the drop tower ride "La Tour Eiffel" suffering cranial trauma and died on the way to the hospital. Initial investigations suggested the possibility of mechanical failure in the restraint latch.[7][needs update]
  • On the evening of January 3, 2018, 8 persons (five females and three males aged 12 to 18, including Danica Villas) were injured suffering "cervical spasms" after Fun Drop Tower Ride at the amusement park Circle of Fun in Quezon Memorial Circle suddenly dropped.[8][9]
  • On the evening of September 5, 2021, 6-year-old Wongel Estifanos died on the Haunted Mine Drop ride after being separated from her seat and falling 110 ft (34 m) to her death. It has been determined that the girl was actually sitting on top of her seatbelt rather than the seatbelt being tight on her lap. A forensic pathologist identified the cause of death as blunt-force trauma. The official report by the Colorado Division of Oil and Public Safety blamed a lack of procedures and inadequate training of two ride operators to ensure that Estifanos was properly buckled in.[10][11] Before the accident, the ride had had four annual safety inspections per Colorado Amusement Rides and Devices Regulations (7 CCR 1101-12) and was certified to have corrected any issues.[11] Following the incident the park temporarily closed.[12][13][14] Colorado Senate Bill 03-253 allows parents to release their minor’s rights to sue for negligence.[15][16]
  • On the evening of March 24, 2022, 14-year-old Tyre Sampson from Missouri fell to his death from the world's tallest drop tower ride, the Orlando FreeFall drop tower at ICON Park in Florida. The brand new attraction had been open for only three months at the time of the accident.[17] On April 18, 2022, it was discovered that the safety sensors of two seats were intentionally modified to generate a "go" signal for larger and therefore unsafe harness-to-seat gaps, presumably to accommodate larger riders, a condition that ultimately led to Tyre's death, since he slipped through that gap toward the end of the drop when the ride slowed down.[citation needed] This is only one major factor among others that may have caused the tragedy, including the fact that Tyre weighed 320 pounds (144 kg) and the ride manual stipulates a weight limit of 287 pounds (130 kg).[citation needed] On October 6, 2022, it was announced that the Orlando Free Fall tower would be dismantled.[18] The owner plans to have the demolition finished by the anniversary of the victim’s death.[19]
  • On September 5, 2022, a drop tower in India failed to slow down then crashed to ground, injuring 16.[20]
