Airman 1st Class Sharrad Smith, a 362rd Training Squadron A-10 crew chief apprentice Airman, inspects the cockpit of an A-10 Thunderbolt II at Sheppard Air Force Base, Texas, Jan. 5, 2018. Smith was performing a pre-flight check, which includes testing the flaps, munitions systems, control panels and more to see if the plane is in flying condition. The pre-flight check is one of many routine checks a crew chief must perform before giving the plane approval for flight. (U.S. Air Force photo by Airman 1st Class Pedro Tenorio)
