Airman Brandon Stevens, 365th Training Squadron A-10 fighter avionics course student, receives guidance from instructor Staff Sgt. Bobby Campbell as he performs a safe-for-maintenance check at Sheppard Air Force Base, Texas, August 2, 2018. A safe- for-maintenance check is an inspection performed to ensure all safety pins are in place and the power is functioning properly before the official inspection of the aircraft can occur. Stevens said this was his first time sitting in the flight deck and he enjoyed seeing how complex all the controls are. (U.S. Air Force photo by Airman Madeleine E. Remillard)
