Airmen from Shaw Air Force Base, S.C., and Mountain Home Air Force Base, Idaho, begin their day of work shortly after being dropped off on the flight line at Tyndall Air Force Base, Fla., Nov. 6, 2017. Airmen from more than eight bases across the United States were sent on a temporary duty assignment to Tyndall to participate in Checkered Flag 18-1, a two-week, large-scale exercise that integrates the warfighting power of both fourth- and fifth- generation aircraft, and the concurrently running Weapon Systems Evaluation Program, Combat Archer.
