F-15 - Air surveillance

OVER ALASKA—Two F-15 Eagles from Elmendorf Air Force Base, Alaska, intercept a C-21 on Aug. 15 during Alaska Shield/Northern Edge 05. The exercise is the largest homeland defense/homeland security exercise conducted in Alaska. It is an opportunity within the state to exercise an integrated local, state and federal government response to a series of simulated emergencies. (U.S. Air Force photo by Staff Sgt. Shane Heiser)
