Stinson Detroiter

The Stinson Detroiter was a family of cabin aircraft built by the Stinson Aircraft Company of Detroit in the later 1920s. The first, the SB-1, was a biplane with an enclosed, heated cabin that first flew on 25 January 1926 with a Wright Whirlwind engine, and 26 aircraft followed the prototype. The better known SM-1 was a six-seat high-wing monoplane designed by William C. Naylor from the SB-1 fuselage and first flown in April 1927. Seventy-five were built with the Wright J-5 engine and thirty with the J-6, and Braniff Air Lines and Northwest Airways flew them on scheduled services from 1928. Variants included the diesel-powered SM-1DX, the first diesel aircraft to fly, the larger SM-6 and the smaller SM-2 Junior.
