First Lt. Caesar, 34th Bomb Squadron weapon systems officer, undergoes parachute drag training at the Bellamy Fitness Center indoor pool at Ellsworth Air Force Base, S.D., Feb. 9, 2016. In order to fly on an aircraft, aircrew members must receive annual Survival, Evasion, Resistance, and Escape refresher training to keep their minds sharp and well prepared. This starts off with academics before moving on to hands-on training. (U.S. Air Force photo by Airman Donald C. Knechtel/Released)
