SUMMARY: It's been a little over a week since NASA's X-43A hypersonic research aircraft made its successful flight, and the flight data is really impressing the agency. The X-43A was accelerated on board a Pegasus rocket, and then it fired its airbreathing scramjet engine to briefly raise its speed to Mach 7 (8,575 kph). While the data proves that the engine definitely worked, reality differed from the engineers simulations in several respects; more flight tests are scheduled to better understand the dynamics of hypersonic flight.
