Rearwin
Rearwin Airplanes was founded by Raymond Andrew (“Rae”) Rearwin in 1928, at Salina, KS.
Following Charles Lindbergh’s historic transatlantic flight in 1927, the world’s fascination with aviation grew significantly. Moreover, the Air Commerce Act of 1926 established the government certification program of pilots and aircraft that gave the fledgling industry safety and legitimacy.
Rearwin produced Junior two-seat light monoplane in 1931, followed by Speedster with American Cirrus engine.
Employing his two sons, Royce and Ken, the small company designed and built over 400 airplanes, including instrument trainers and gliders, despite the effects of the Great Depression.
Taken over in 1935 by partnership called Rearwin Airplanes. In 1937 bought assets of Le Blond Aircraft Corporation renamed as Ken-Royce motors. 1939: Renamed Rearwin Aircraft & Engines Inc.
Rae Rearwin sold the company to the Empire Ordinance Company in 1942. The company built about 275 more Skyrangers under the Commonwealth name before they closed their doors in 1946.
