Practicing precision
SOUTHWEST ASIA -- Staff Sgt. Andrea Lopez prepares to turn a digital test set on its side so she can inspect its circuit cards. The test set, which checks out guidance systems on missiles, was brought to the precision measurement equipment laboratory because of power-up and self-test failures. Sergeant Lopez is a PMEL technician with the 379th Expeditionary Maintenance Squadron and is deployed from Aviano Air Base, Italy. (U.S. Air Force photo by Senior Airman Chawntain Young)
