Jim Crawford, an outside machinist with the Aerospace Testing Alliance (ATA) Flight Systems Operation and Maintenance branch, inspects a winglet on the wingtip of the C-5M Super Galaxy model during a break in testing in Arnold Engineering Development Complex’s (AEDC) 16-foot Transonic Wind Tunnel (16T). The model is a pink color as a result of AEDC’s application of Pressure Sensitive Paint (PSP) to it before the test was conducted. (Photo by Rick Goodfriend)
