Tennessee Air National Guard Master Sgt. Roy Roberts, a flight engineer for the 118th Airlift Wing, points out some differences in the configuration of a C-130 Hercules ???Super E" aircraft to Kentucky Air National Guard Staff Sgt. Daniel Wormley, a flight engineer for the 165th Airlift Squadron, at the Kentucky Air National Guard Base in Louisville, Ky., on July 26, 2012. The Kentucky Air National Guard, which already flies the C-130 ???H??? model, acquired the older Super E aircraft from the Tennessee Air National Guard.
