The P-29 aircraft was an attempt to improve the basic P-26 design. The Boeing Model 264 was tested by the Army Air Corps as the XP-940 and featured an all-metal construction, enclosed cockpit and retractable landing gear. Three aircraft were ordered (S/N 34-23, 24 and 25) to test various configurations. The original XP-940 aircraft (S/N 34-24) was modified to an open cockpit and became the XP-924 test project (YP-29A) and was later modified with a new engine to become the P-29A. The second aircraft (S/N 34-23) was an improvement of the basic XP-29 design and first flew as the YP-29 and later as the P-29. This aircraft had an enclosed "greenhouse" canopy, wing flaps and a different engine, but its performance was unsatisfactory. The final aircraft (S/N 34-25) was a development of the YP-29 with an open cockpit and new wing but also proved unsatisfactory.
