The Savoia-Marchetti S.64 was a monoplane developed in Italy in 1928 specifically to contest the world duration and distance records. It was an unusual pod-and-boom design, with the empennage carried on two open truss structures that extended aft from the wings, similar to the arrangement used on the S.55. The powerplant was mounted on a set of cabane struts above the wing, and consisted of a single engine driving a pusher propeller.
