U.S. Air Force Capt. Carl Johnson, a B-52 navigator assigned to the 2nd Operations Group at Barksdale Air Force Base, La., prepares for the first flight of a B-52H Stratofortress that is being regenerated at the 309th Aerospace Maintenance and Regeneration Group on Feb. 12, 2015, Davis-Monthan Air Force Base, Ariz. The B-52 was decommissioned in 2008 and has spent the last seven years in 1000-type storage in the "Boneyard,” but is being restored and will eventually join the active B-52 fleet.
