Ryan M-1

From servicing its planes, Ryan Airlines went into modifying them; and from modifying to building Ryan's own design, the fast, clean M-1 monoplane. The Ryan M-1 first flew on February 14, 1926, and 16 were built for use on the early Western air routes. The M-1 was reputedly a difficult aircraft to fly, but it led ultimately to one of the most famous aircraft in the world, the Ryan Spirit of St. Louis.
Built by B. F. Mahoney Aircraft Corporation, San Diego.
