Actually the X15 was about twice as fast as the SR71. The X15 hit about 4.5k and above mach 6.
The SR71 was the fastest manned jet ever produced as far as we know. The X15 was powered by liquid-propellant rocket. The new leader in speed us now the NASA X-43, but is unmanned and hit speeds of over 7K
