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 being used on Boeing's airmail routes.
Development
While the Model 95 was of the same general configuration as the Model 40, it was larger and more sophisticated aerodynamically and structurally, and was optimized for freight instead of passengers. The fuselage was of far more advanced construction than its predecessor, building on what Boeing had learned about all-metal fuselages while developing the P-12 and F4B fighters, while the wing had stagger and a simplified structure.
Operational history
The majority of Boeing 95s spent their careers flying Boeing's airmail routes, however a small number did find their way to other operators. At least one Boeing 95 was used by the Honduran Air Force as a bomber. Another Model 95 took part in Boeing-arranged inflight refuelling demonstrations in 1929 but was unsuccessful in either of the two attempts made to fly a round-trip across the continental United States without landing.
