Contributor:

ww2dbaseIn response to the 1938 United States Army request for a new observation aircraft, the firm Ryan Aeronautical Company developed the YO-51 Dragonfly. Three prototypes were made and sold to the US Army for evaluation, and the first took flight in 1940. Ultimately, the US Army chose O-49 (later L-1) Vigilant aircraft made by Stinson Aircraft Corporation, and the YO-51 Dragonfly project was scratched.
