This formation photograph documents cadets and instructors assembled outside the hangar of Johnson's Flying Service, a civilian contract airfield in Greenwood, South Carolina, that provided primary flight training to military aviation cadets during World War II. Painted signage advertising Piper Cub sales and student instruction reflects the wartime partnership between civilian aviation businesses and the armed forces, which relied on such contract schools to train the large numbers of pilots needed for the war effort.
