Boeing Stearman VN2S-2 at the Hahnweide Oldtimers Meet 2011.
The Stearman (Boeing) Model 75 is a biplane, of which at least 9,783 were built in the United States during the 1930s and 1940s as a military trainer aircraft. Stearman Aircraft became a subsidiary of Boeing in 1934. Widely known as the Stearman, Boeing Stearman or Kaydet, it served as a primary trainer for the USAAF, as a basic trainer for the USN (as the NS & N2S), and with the RCAF as the Kaydet throughout World War II. After the conflict was over, thousands of surplus aircraft were sold on the civil market. In the immediate post-war years they became popular as crop dusters and as sports planes.
The cowling on this aircraft is not an original Stearman and it could be confused with a Waco who uses that cowling type.
