Boeing Model 64

The Boeing Model 64 was an American biplane training aircraft built by Boeing.

Development and design
The Model 64 was built by Boeing at their own expense, and submitted to both the US Army and Navy as a primary and gunnery training aircraft. The fuselage and tail was constructed of welded steel tubing, with wood wings spars and ribs. The wings used were an older version, due to stalling issues in the Model 21, and were thin enough to require two bays of bracing struts. For gunnery training a removable rear cockpit structure was built to carry a mounting ring and flexible machine gun. A fixed gun could also be mounted at the front and synchronized to fire through the propeller.

The Model 64 first flew in February 1926. Later the wings were replaced with a thicker airfoil (Munk M-12 NACA) which required only one set of struts. The updated plane first flew on 31 August 1926.

The aircraft was sold to Pacific Air Transport, later fitted with an Wright J-5 engine and resold to a private owner.
