Airman 1st Class Tye Braden, 19th Maintenance Squadron nondestructive inspection journeyman, calibrates an ultrasonic device on Little Rock Air Force Base, Ark., Apr. 10, 2018. The ultrasonic device send out sound waves and when the waves are bounced back at a certain frequency, NDI Airmen know that they’ve found a crack.
