An F-15 Eagle assigned to Barnes Air National Guard Base, Westfield, Mass., takes off Dec. 7, 2013, from Westover Air Reserve Base at Chicopee, Mass., heading toward an annual exercise in Florida. The jets flew training missions out of Westover ARB for approximately six months while the runway at Barnes Municipal Airport was undergoing several months of repairs. The F-15 is an extremely maneuverable, all-weather tactical fighter designed to permit the Air Force gain and maintain air superiority. (U.S. Air Force photo/Staff Sgt. Kelly Goonan)
