Two of 14 U.S. Air Force F-16 Fighting Falcon aircraft with the 18th Aggressor Squadron prepare to take off from Eielson Air Force Base, Alaska, shortly after sunrise Jan. 17, 2015, in transit to Joint Base Pearl Harbor-Hickam, Hawaii, and Andersen Air Force Base, Guam, to participate in the Sentry Aloha and Cope North exercises. More than 150 maintainers will keep the Aggressors in the air during the exercises, which are meant to prepare U.S. Airmen, Sailors and Marines along with coalition partners in the Pacific theater of operations for contingency operations if the need arises.
