A B-52 Stratofortress undergoes a bag lift exercise at Barksdale Air Force Base, La., Feb. 16, 2017. A pneumatic lifting bag raises an aircraft that has experienced a landing gear failure or from terrain where it is impractical or impossible to use standard aircraft jacks. Air Force Global Strike Command, 2nd Bomb Wing, 307th Bomb Wing and Sheppard Air Force base combined their efforts to lift a B-52 that was damaged in a fire more than two years ago. This raise has not been attempted since 1984. (U.S. Air Force photo by Tech. Sgt. Ted Daigle/Released)
