According to my source: "The SR-71 "Blackbird" holds the official Air Speed Record for a manned airbreathing jet aircraft with a speed of 3,529.56 km/h (2,188 mph). It was capable of taking off and landing unassisted on conventional runways. The record was set on 28 July 1976 by Eldon W. Joersz near Beale Air Force Base, California, USA.[2]"

I heard of the US Air Force Scram Jet that goes Mach 10. That's right Mach 10. Its the fastest aircraft in the world.

The Lockheed/USAF SR-71 (now retired). The first aircraft to use ramjet/turbojet engines, it has acheieved level flight speeds around Mach 4.
Also known as the "Blackbird" it was used for about 30 years for high-altitude reconaissance. overflying pretty much anybody--including the old Soviet Union. In that time, around 4000 attempts were made to shoot one down--but no one has ever been able to build an anti-aircraft missle fast enough to catch it.

Recent scram-jet engines have the potential to reach speeds above mach 7, (been tested bolted onto rockets), but at this point have not been successfully tested on aircraft.

For manned flight it would be the X-15 which reached a speed of 7,274 km/h (4,520 mph). Though it did reach altitude of over 50 miles (80 km) so I guess it would be considered a space craft.
