The Douglas XB-42 Mixmaster was an experimental bomber aircraft designed for a high top speed. The unconventional approach was to mount the two engines within the fuselage driving a pair of contra-rotating propellers mounted at the tail leaving the wing and fuselage clean and free of drag-inducing protrusions.Two prototype aircraft were built but the end of World War II changed priorities and the advent of the jet engine gave an alternative way toward achieving high speed.
