Aircrew members assigned to the 34th Bomb Squadron perform pre-flight checks during a walk-around-inspection of a B-1 bomber as part of a stand-off weapons integration exercise at Ellsworth Air Force Base, S.D., Aug. 13, 2014. The stand-off weapons integration training exercise was developed by B-1 aviators, and B-52 Stratofortress bomber crews assigned to the 23rd Bomb Squadron, Minot Air Force Base, N.D., to create an integrated mission plan involving simulated tactical scenarios to train for potential future operations.
