Mach 10

Defense Tech mentions a story from Wired, reporting:
> “NASA will attempt to break the aircraft speed record next week by flying a jet plane at 7,000 mph, or nearly 10 times the speed of sound,” Wired News says.
>
> The unmanned flight will mark the third time NASA has tested its new supersonic-combustion ramjet, or “scramjet,” engine, which has no moving parts and emits only water as exhaust.

Update: They did it!
