Air Force Senior Airman Eric Madlangbayan, an aircraft hydraulic technician journeyman with the 446th Aircraft Maintenance Squadron, McChord Field, Wash., deftly pulls the lever to open a C-17 Globemaster III aircraft troop door during his aircraft hydraulics inspection. Airman Madlangbayan described aircraft hydraulic technicians as a close-knit team, because they work in high pressure settings, and have to have strong communication skills.
