Strong sold military versions of the tower to the Romanian and U.S. armies, as well as installed towers in New Jersey and Fort Benning, Georgia. He converted an existing observation tower in Chicago's Riverview Park into a six-chute amusement ride. This enterprise, the "Pair-O-Chutes", performed well enough that Strong applied to build and operate a jump at the 1939 New York World's Fair. Another jump, also reportedly designed by Strong, was installed at the Exposition Internationale des Arts et Techniques dans la Vie Moderne in Paris in 1937.
