It was described in the 1939 Fair guidebook:
Eleven gaily-colored parachutes operated from the top of a 250-foot tower, enable visitors to experience all the thrills of "bailing out" without the hazard or discomfort. Each parachute has a double seat suspended from it. When two passengers have taken their places beneath the 'chute, a cable pulls it to the summit of the tower. An automatic release starts the drop, and the passengers float gently to the ground. Vertical guide wires prevent swaying, a metal ring keeps the 'chute open at all times, and shock-absorbers eliminate the impact of the landing. One of the most spectacular features of the Amusement Area, this is also a type of parachute jump similar to that which the armies of the world use in early stages of training for actual parachute jumping.
