NDI Airmen finding the cracks

Staff Sgt. Benjamin Reeves, 22nd Maintenance Squadron nondestructive inspection craftsman, uses a Sonic 1200 ultrasonic flaw detector to measure the aluminum thickness standard May 28, 2020, at McConnell Air Force Base, Kansas. The NDI flight uses the equipment that emits ultrasounds to determine a part’s thickness and to identify subsurface cracks measuring 0.005 inches.
