The Ryan factory was opposite Consolidated's at then Lindbergh Field. The Ryan YO-51 was designed to meet a 1938 USAAC requirement for an observation aircraft and clearly influenced by the Fieseler Storch. The competition was won by the Stinson Vigilant and only three YO-51s were built, this being the first one, 40-703, according to the San Diego Air & Space Museum.
