351st EARS maintainers keep tanker cool
Senior Airman William Studley, 100th Maintenance Squadron, finishes installing the air cycle machine (ACM) on a KC-135 Stratotanker while deployed with the 351st Expeditionary Air Refueling Squadron April 18, 2013, in Southwest Europe. The ACM feeds air into the fuselage and cockpit of the aircraft to help regulate the internal temperature and climate during flight, which helps keep the aircraft fully functional.
