The story
The Kreider-Reisner Aircraft Company was formed at Hagerstown, Maryland, in 1923 as a sub-contractor. By September 1925 the company was operating a general flying service and incorporated. In 1926 it designed and built the first aircraft the Midget lightplane. The aircraft performed well in aviation competitions so the company then designed a two-seat utility biplane. It had decided it was cheaper to design and build an aircraft for use in its own flying services and the resulting aircraft was the C-2 Challenger. A smaller version was designed and built in 1928 as the C-6 Challenger. On 1 April 1929 the company was bought by the Fairchild Aircraft Company who continued production at Hagerstown and redesignated the aircraft in a Fairchild KR series. Kreider remained president, but died on 13 April 1929 in a mid-air collision. Reisner left the company shortly afterward. By 1931, Fairchild had relocated its headquarters to the Hagerstown site. In 1935, the name of the company was changed to Fairchild Aircraft Corporation.
