X-43A: NASA Goes Hypersonic
"NASA's X-43A research vehicle screamed into the record books ... [in November 2004], demonstrating an air-breathing engine can fly at nearly 10 times the speed of sound. Preliminary data from the scramjet-powered research vehicle show its revolutionary engine worked successfully at nearly Mach 9.8, or 7,000 mph." The site includes information about scramjet technology, mission news, articles, photos, and video clips. From the National Aeronautics and Space Administration (NASA).
