Flight Test Files

Flight Test Files is a series that looks closely at the aircraft flown by NACA and later NASA at the High-Speed Flight Station in Edwards, California, known today as the Armstrong Flight Research Center. These were not always purpose-built research airplanes. Many were operational fighters, bombers, or transports that were brought to the desert to answer specific technical questions. Each article focuses on what problem NACA/NASA engineers were trying to solve, why a particular aircraft was chosen, what the flights revealed, and how it changed the future of aviation.
