Col. Gentry Boswell, 28th Bomb Wing vice commander, and Airman Deonaraine Singh, 28th Aircraft Maintenance Squadron hydraulics technician, and the youngest Airman on base, cut a birthday cake during a celebration in honor of the Air Force’s 66th birthday in the Raider Café at Ellsworth Air Force Base, S.D., Sept. 18, 2013. The cake-cutting tradition has long since symbolized the passing down of wisdom from senior to junior servicemembers. (U.S. Air Force photo by Airman 1st Class Zachary Hada/Released)
