History
The Boeing Model 248, which became the P-26 series, was designed in 1931 and first flew in 1932, and was one of the first monoplane fighters adopted by the U.S. Army Air Corps to replace such classic biplane fighters as the Curtiss Hawk and Boeing P-12. Retaining some of the features of previous fighters (including an open cockpit, external wire bracing, fixed landing gear, and fixed pitch propeller), the P-26 set the standard for fighters at the time of its introduction. More than anything else, it helped to establish the monoplane as the standard of excellence in design, and most designers throughout the world were at least somewhat influenced by this fighter.
