Airman 1st Class Connor Duffey, a non-destructive inspection journeyman with the 1st Special Operations Maintenance Squadron, uses a probe to calibrate an eddy current that will be used to inspect damaged aircraft parts at Hurlburt Field, Fla., April 9, 2018. An eddy current is a device that uses electromagnetic methods in non-destructive testing. The NDI specialists use dye penetrants, magnetic particles and eddy currents to discover cracks in aircraft parts that go unseen by the naked eye. ( Air Force photo by Airman 1st Class Dennis Spain)
