Airman Dylan Senne, 363rd Training Squadron F-16 aircraft armament systems apprentice course student, helps load an air intercept missile onto an aircraft at Sheppard Air Force Base, Texas, May 1, 2019. To ensure the safety of anyone who comes in contact with a loaded aircraft, munitions must be secured in place. During the course, students train with both aircraft and munitions to make sure they are proficient in AIM-9 loading and downloading. (U.S. Air Force photo by Senior Airman Ilyana A. Escalona)
