The original XP-82 Twin Mustang, (AF s/n 44-83887), is currently being restored to flying status by the B-25 Group at Douglas Municipal Airport in Douglas, Georgia. Headed up by aircraft restorer Tom Reilly, the project is well underway. A hat-tip to Warbirds News for the reminder that there are many dedicated people out there keeping our aircraft history flying.
This aircraft is only one of two that still exist in civilian hands.
About the F-82 from Wikipedia:
The North American F-82 Twin Mustang was the last American piston-engine fighter ordered into production by the United States Air Force. Based on the P-51 Mustang, the F-82 was originally designed as a long-range escort fighter in World War II; however, the war ended well before the first production units were operational, so its postwar role changed to that of night-fighting. Radar-equipped F-82s were used extensively by the Air Defense Command as replacements for the Northrop P-61 Black Widow night fighter. During the Korean War, Japan-based F-82s were among the first USAF aircraft to operate over Korea. The first three North Korean aircraft destroyed by U.S. forces were shot down by F-82s, the first being a North-Korean Yak-11 downed over Gimpo Airfield by the USAF 68th Fighter Squadron.
