The aircraft that enjoyed what was perhaps the longest and most successful career in air racing history was Steve Wittman's Chief Oshkosh, known in the post-World War II era as Buster. From 1931 until its retirement in 1954, this midget racer set records and took numerous trophies in class races and free-for-alls. Painted on the engine of the Wittman Special 20 are the words “buster by S.J. Wittman Oshkosh, WIS.”
