On th job
Kim Luther, an Aerospace Testing Alliance Test Operations systems engineer for the center’s 16-foot transonic wind tunnel, inspects a 16T High Angle Automated Sting (HAAS) pitch blocking valve. She is in the process of completing a job that replaced four of these valves due to performance issues. The valves have been in place for more than 20 years and had never been removed, rebuilt or replaced. (Photo by David Housch)
