The shorter towers are used by trainees jumping in harnesses with a fall-restraint cable to simulate the exit from an aircraft and safe landing technique.
[1] The high tower typically has one or more arms at the top from which the trainee is winched up into the air and released to descend by parachute.
The trainee is hauled up into the air and dropped to free fall approximately 15 feet (4.6 m) before being brought to a complete stop.
[1] After high tower training is passed troops proceed onto aircraft jumps from an altitude of approximately 1,250 feet (380 m).
[6][3] Major William Lee of the United States Army, in charge of the training of the first 48-man platoon of US paratroopers, saw the Parachute Jump ride and constructed a similar tower at Fort Benning.
[7] Some of the Polish Army escaped to the United Kingdom after the fall of Poland[8] and was based at Largo House, Scotland.
[22][23][24][25] Intamin also produced a "Parachute Drop" for Knott's Berry Farm in California in the late 1970s, which was named "Sky Jump".
[28] Tokyo Dome City Attractions, Japan, has an Intamin parachute drop ride named Sky Flower.
