Staff Sgt. Joshua Paserba, 86th Maintenance Squadron nondestructive inspection technician, performs a step in the penetrant inspection process, July 31, 2013, Ramstein Air Base, Germany. This part in the process uses an emulsifying bath, which removes traces of excess penetrant, allowing crack indications to be more readily visible. (U.S. Air Force photo/Senior Airman Chris Willis)
