Wiki Says....

The Stearman (Boeing) Model 75 is a biplane used as a military trainer aircraft,
of which at least 10,626 were built in the United States during the 1930s and
1940s. 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
United States Army Air Forces, the United States Navy (as the NS & N2S), and
with the Royal Canadian Air Force as the Kaydet throughout World War II. After
the conflict was over, thousands of surplus aircraft were sold on the civilian
market. In the immediate postwar years they became popular as crop dusters,
sports planes, and for aerobatic and wing walking use in air shows.

The Kaydet was a conventional biplane of rugged construction with large, fixed
tailwheel undercarriage, and accommodation for the student and instructor in
open cockpits in tandem. The radial engine was usually uncowled, although some
Stearman operators choose to cowl the engine, most notably the Red Baron
Stearman Squadron.

Operational history

Post-war usage

After World War II, the thousands of primary trainer PT-17 Stearman planes were
auctioned off to civilians and former pilots. Many were modified for cropdusting
use, with a hopper for pesticide or fertilizer fitted in place of the front
cockpit. Additional equipment included pumps, spray bars, and nozzles mounted
below the lower wings. A popular approved modification to increase the maximum
takeoff weight and climb performance involved fitting a larger Pratt & Whitney
R-985 Wasp Junior engine and a constant-speed propeller. An iconic movie image
is a Stearman cropduster chasing Cary Grant across a field in North by
Northwest. Christopher Reeve and Scott Wilson are shown flying 1936 variants in
the 1985 movie The Aviator.
