Naval Aviation Cadets report for training at Sam Houston Airport, Houston, Texas, home of the civilian-operated Cliff Hyde Flying Service. During World War II, the U.S. Navy's V-5 Naval Aviation Cadet program contracted with commercial flying schools like this one to provide primary flight instruction and elimination screening, testing candidates' aptitude before they advanced to formal naval flight training. The hangar's painted sign advertising repair, instruction, and pleasure-ride services reflects the dual civilian-military role such fields played during the war. Project: 218571
