The second seat was easily accommodated in the roomy cockpit. [Source: NMNA] Although testing of the promising XF8B concept continued into 1946 by the USAAF and 1947 by the US Navy, the end of the war in the Pacific and changing postwar strategy required that Boeing concentrate on building large land-based bombers and transports. The advent of jet fighters led to the cancellation of many wartime piston-engined projects; consequently, since the USAF lost interest in pursuing the project and the U.S. Navy was only prepared to offer a small contract, Boeing chose to wind down the XF8B program. Tests at Boeing Field were marred by an accident in which a test pilot accidentally retracted his landing gear on final approach. Investigation later found this to have been caused by a faulty micro switch. This occurred just as first shift was ending, and as many workers watched from the Plant 2 steps, the XF8B-1 bellied onto the concrete of Boeing Field. As the test program was concluded, the prototypes were scrapped one by one, with Bu. 57986 lingering on into 1950.
