Boeing Model 95

The Boeing Model 95 was a single-engine biplane mailplane built by Boeing in the United States in the late 1920s to supplement the Boeing Model 40s flying Boeing's airmail routes. It had the same general configuration as the Model 40 but was larger, more sophisticated aerodynamically and structurally, and optimised for freight rather than passengers. Its fuselage was of far more advanced construction, building on what Boeing had learned about all-metal fuselages while developing the P-12 and F4B fighters, and its wing had stagger and a simplified structure. Most Model 95s spent their careers on Boeing's airmail routes, though a few reached other operators; at least one served the Honduran Air Force as a bomber, and another took part in Boeing-arranged inflight refuelling demonstrations in 1929. A single Model 95A was built with a Pratt & Whitney Wasp engine.
