US Air Force/Kelly White "Ghost Rider" and "Wise Guy," the only B-52 Stratofortress bombers to be resurrected from the Air Force's "boneyard," are undergoing maintenance before returning to Minot Air Force Base. Both were retired to the 309th Aerospace Maintenance and Regeneration Group in Arizona and were never to fly again, but they've been resurrected to bring the fleet back to the Congressionally mandated 76 B-52s. Only two B-52 Stratofortress bombers have been restored out of the Boneyard to be returned to the fleet: "Ghost Rider," tail number 61-0007, and "Wise Guy," tail number 60-0034. Both aircraft were retired at the 309th AMARG (Aerospace Maintenance and Regeneration Group) at Davis-Monthan AFB, Arizona, where they were supposed to remain to be cannibalized of parts needed by other front-line BUFFs and never to fly again.
