The Beechcraft Baron is a light, twin-engined piston aircraft originally developed by Beech Aircraft Corporation and currently manufactured by the Hawker Beechcraft Corporation, an Onex Holding Corporation. The Baron is a variant of the Beechcraft Bonanza, more specifically the Travel Air, and was introduced in 1961. Beech also offered a Twin Bonanza line; they featured some design commonality with the Bonanzas, but in all respects were entirely different airplanes and could not be considered to be true "Twin Bonanzas".
