Col. Ty Neuman, 28th Bomb Wing vice commander, and the youngest Airman on base Airman 1st Class Evan Meija, 37th Aircraft Maintenance Unit crew chief, cut a birthday cake during a celebration in honor of the Air Force’s 67th birthday in the Raider Café at Ellsworth Air Force Base, S.D., Sept. 18, 2014. The cake-cutting tradition symbolizes the passing down of wisdom from senior to junior servicemembers, a key element of Air Force heritage.
