During the 1930s and 1940s, the airport site was used both for aviation and farming. In 1941, the airport hangar was sold to Ferris Thomas, and in 1942 the operations were sold to Elmer Wood. In 1943, H.F. Wattenbarger purchased the property for use as a farm, but that same year he began leasing the airport for wartime training of 300 Army Air Cadets. After the training program ended, Wattenbarger resumed operation as a private airport and farm. Robert Campbell, owner and operator of Campbell’s Aero Service, became the airport's primary operator in the late 1940s, continuing for nearly two decades.
