Two Airmen monitor air pressure gauges for a bag lift exercise at Barksdale Air Force Base, La., Feb. 16, 2017. A B-52 Stratofortress was lifted, for the first time since 1984, with large inflatable airbags to simulate how to recover a jet experiencing a landing gear failure. More than 30 Airmen from Barksdale, Sheppard and Edwards Air Force Bases participated in the exercise. (U.S. Air Force photo by Tech. Sgt. Ted Daigle/Released)
