U.S. Air Force Airman 1st Class Brandon Long, a 354th Maintenance Squadron non-destructive inspection (NDI) apprentice, conducts a daily calibration on a magnetic particle machine Nov. 8, 2017, at Eielson Air Force Base, Alaska. The NDI shop is part of the 354th Maintenance Group, and while they don’t turn a wrench or swing a hammer, their mission takes precedence when unknown flaws need to be found.
