A class of aviation trainees poses in front of Johnson's Flying Service, a civilian-operated flight school that, like many such businesses across the country, contracted with the US government to provide primary flight instruction to military aviation cadets. Rows of Piper Cub trainers are visible under the hangar doors behind the group. Programs such as the Civilian Pilot Training Program and the Navy's V-5 Aviation Cadet program relied on civilian schools like this one to teach the fundamentals of flight before cadets advanced to military flight training, producing thousands of pilots for wartime service.
