An in-flight photo of the NASA F-15A with a 10-degree cone to collect aerodynamic information to calibrate data from wind tunnels. NASA obtained the “A” model from the U.S. Air Force on Jan. 5, 1976, and used it for more than 25 advanced research projects involving aerodynamics, performance, propulsion control, control integration, instrumentation development, human factors, and flight test techniques.March 20, 1980NASA Photo› F-15A Project Description
