One of the second world war's odder ducks, the P-82 Twin Mustang was developed as an extreme long range escort for B-29 bombers in the Pacific. To support this longer range, it had cockpits for two pilots so that each one could get an occasional rest along the way. It arrived late, and the capture of Pacific island bases enabled the use of regular P-51 Mustangs for this escort duty, but after the war the long range and high speed of the Twin Mustang made it a valuable fighter during the transition period from piston to jet powered aircraft. The first air-to-air victories of the Korean War were scored by the P-82 in 1950. It was withdrawn from service in 1951 as jet fighters became available.
