U.S. Air Force Master Sgt. Steve Vance, 307th Aircraft Maintenance Squadron crew chief, disconnects a tow bar from a B-52H Stratofortress after towing it to a parking spot on the flight line at Davis-Monthan (DM) Air Force Base, Ariz., Feb. 11, 2015. The aircraft was decommissioned in 2008 and sent to the "Boneyard" at the 309th Aerospace Maintenance and Regeneration Group at DM, but is now being restored and is expected to return to active service in 2016.
