Randy Vinke, an ATA electrician with the Propulsion Wind Tunnel Facility Test Operations group at Arnold Engineering Development Complex, installs wires for the interface panels that are used to connect the test model instrumentation to a data system. The installation occurs in the PWT four-foot Transonic Wind Tunnel Captive Trajectory Support, or CTS, system, which contains a newly designed and fabricated mechanism that enables a test model to have six degrees of motion: pitch, roll, yaw, axial, horizontal and vertical. The CTS is used to conduct staging and store separation testing. (U.S. Air Force photo/Rick Goodfriend)
