Nondestructive inspection Airmen use a transducer to check for imperfections on an F-35A Lightning II panel at Eglin Air Force base Fla., May 16, 2016. This piece of equipment uses sound vibrations to check for cracks in the inner layers of metal on a jet that may go unnoticed by the naked eye. If there is underlying damage, the Sonic 1200 unit will reflect the depth of damage in need of repair. (U.S. Air Force photo/Senior Airman Andrea Posey)
