Mach 10 will be amazing... Of course - who knows what other black projects are out there and what they can do... :alien:

There's still problems before aircrafts flying these speeds are possible.
[quote]When the second X-43A research vehicle flew Mach 6.83, or nearly seven times the speed of sound (the speed of sound is about 760 mph at sea level), the friction-generated 2600-degree Fahrenheit temperature on the leading edges of the vehicle's horizontal tails was more than enough to melt unprotected metal...
When the third and final X-43A flies in November, blistering temperatures created by the Mach 10 (7000 mph) speed will be in the neighborhood of 3600 degrees, the hotspot this time being the nose of the vehicle.[/quote]
