Non-destructive inspections Airmen see the unseeable, keep KC-135 flying
U.S. Air Force Airman 1st Class Patrick Torres, 92nd Maintenance Group non-destructive inspection technician, tests a piece of metal with a magnetic machine to see if it detects holes through the metal at Fairchild Air Force Base, Washington, Sept 9, 2019. The material tested will show a neon line across the top if magnets indicate there is a hole in the piece of material being tested. (U.S. Air Force photo by Airman Kiaundra Miller)
