The Stearman "Kaydet" was the primary trainer for American pilots during World War Two.

The design, based on the an earlier plane "the Cloudboy" by aeronautical engineer Lloyd Stearman, won the Army and Navy contract. The Boeing Company incorporated Mr. Stearman's company and technically produced the plane with the military calling it the "Kaydet." However, for the many pilots flying this plane they always referred to it as the "Stearman."
