Testing the guinea pig
Staff Sgt. Logan Kendrick, 92nd Medical Support Squadron medical maintenance NCO in charge, removes a component of his office’s test dental sterilizer June 18, 2015, at Fairchild Air Force Base, Wash. Dental sterilizers require a complex interplay of electronics, water and steam that makes their repair requirements sophisticated. (U.S. Air Force photo/Senior Airman Sam Fogleman)
