An F/A-22 Raptor flies over the graduation parade at the U.S. Air Force academy on June 1. It was flown by Lt. Col. Dawn Dunlop, a graduate of the academy's Class of 1988. She is now a test pilot and squadron operations officer at Edwards Air Force Base, Calif., with nearly 100 hours of flying time in the Raptor. [U.S. Air Force photo by Dave Armer]
