quote:
The X-43A is designed to be the first scramjet-powered vehicle, capable of attaining speeds as high as Mach 10. The X-43A mission, first in a series of three, was lost moments after the X-43A and its launch vehicle were released from the wing of the NASA B-52 carrier aircraft. Following launch vehicle ignition, the combined launch vehicle and X-43A experienced structural failure, deviated from its flight path and was deliberately terminated.
