A U.S. Air Force Airman from Mountain Home Air Force

A U.S. Air Force Airman from Mountain Home Air Force Base, Idaho, inspects the canopy of an F-15 Eagle cockpit prior to the arrival of its pilot on the flightline at Tyndall Air Force Base, Fla., Nov. 7, 2017. Airmen from Mountain Home and more than seven other Air Force installations start their days in the early morning hours for Checkered Flag 18-1 and the concurrently running Weapon Systems Evaluation Program, Combat Archer, to maximize the available time to train during the two week long large-scale exercise that integrates the war-fighting power of both fourth- and fifth- generation aircraft with a focus on training for current and future conflicts.
