Stewart Aircraft was formed in 1961 when the Headwind was designed. The name “Headwind” was derived as a bit of fun by naming it the opposite of the Whitman “Tailwind”, a very fast, two place cabin airplane. The Headwind is constructed from steel tube, wood and fabric and is a combination of several designs and concepts developed over a period of several years previous to building the airplane.
