Boeing Model 15 (Paperback)

High Quality Content by WIKIPEDIA articles! The Boeing Model 15 was a United States open-cockpit biplane fighter aircraft of the 1920s, manufactured by the Boeing company. The Model 15 saw service with the United States Army Air Service (as the PW-9 series) and with the United States Navy as a carrier-based fighter (as the FB series). The design of the Model 15 was based on studies of the Fokker D.VII, 142 of which were brought back to the United States for evaluation as part of the Armistice Agreement ending World War I. Many of the features were similar. The Model 15 had a fuselage of welded steel tubing braced with piano wire, while the tapered single bay wings were fabric on a wooden frame, with spruce and mahogany wing spars and 3-ply wood ribs.
