Christopher McCune, 460th Space Wing historian, displays photos of himself and his grandfather during their time in service Sept. 27, 2016, at the 460th Wing Headquarters building on Buckley Air Force Base, Colo. Most Air Force historians possess prior military experience, McCune included, which is helpful to obtaining a security clearance to perform their duties.
