"Ghost Rider," a B-52H Stratofortress that was pulled from the 309th Aerospace Maintenance and Regeneration Group at Davis-Monthan AFB, Ariz., to replace another damaged B-52, arrived at Tinker Air Force Base in December 2015. The historic aircraft spent the last 9 months undergoing extensive repairs in programmed depot maintenance here. The work was completed 90 days ahead of schedule. (Air Force photo by Kelly White)
