Airmen huddle around a binder full of Air Force heritage pictures and stories inside the Airman Leadership School at Ellsworth Air Force Base, S.D., March 20, 2017. During a presentation by Robert Schilling, a former Airman and gunner on the AC-47 “Spooky” during the Vietnam War, students were able to flip through a binder of information about the aircraft, its crew and what they accomplished.
