Actually, I was spoted this thread when looking back for the Valkyrie site I once read and started to love such plane
And yea, I like it much more that the Blackbird, even it is faster and unlike the Valkyrie, it could maintain a little over Mach 3 speed - but still it did not look as great, as Valkyrie do
The plane is purrrfect

About the Mach 6 - this is IMHO does belong to the sci-fi, since AFAIK the rockets have hard time to beat Mach 4 - for example the Russian Sunburns, that threat the US carriers (in fact, they are designed to take them out) have normal fly speed around 2,2 - 2,8 Mach (depending on type, configuration and warhead used - the atomic ones are lighter = slightly faster speed is possible) and closing to the ship at 3 to 3,3 Mach - and even doing "violent close-up manouvers" to prevent being shoot-down before reaching the impact area
Threfore Im very suspicious that anything could travel at Mach 6 at all - at least not close to Earth IMHO.
More informations about top speeds of rockets are welcome anyway
/me like to fly this bejby
