The Alpha was designed as a fast mail/passenger transport aircraft used in the 1930s. Design work was done at the Avion Corporation with a single-engined, all-metal, seven-seat, low-wing monoplane design. In 1929 the company became the Northrop Aircraft Corporation based in Burbank, California. First flight was in 1930 and some 17 aircraft were built flying mainly with TWA but also a few with the US military.
