The Beechcraft C17L Staggerwing was the first aircraft produced by the new Beech Aircraft Company of Wichita, Kansas. It was designed as a high-speed business airplane and had a steel-tube fuselage and wing spar structure. The upper wing was inversely staggered behind the lower wing, a design that gave the airplane its unique shape and name.
