The following is a list of speed records for various types of vehicles.This list only presents the single greatest speed achieved in each broad record category; for more information on records under variations of test conditions, see the specific article for each record category.
At Mach 0.65, u is 65% of the speed of sound (subsonic), and, at Mach 1.35, u is 35% faster than the speed of sound (supersonic).

The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas.
Mach 10 or variation, may refer to: Mach number for ten times the speed of sound Hypersonic speed of 10 times the speed of sound; Mach 10 Training Systems, a coaching consultancy of James McCallum (cyclist) "Mach 10" (song), a 2007 song by Dub Pistols off the album Speakers and Tweeters; MachTen, a Unix-like operating system based on BSD and ...

Simulation of hypersonic speed (Mach 5) While the definition of hypersonic flow can be quite vague and is generally debatable (especially because of the absence of discontinuity between supersonic and hypersonic flows), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow.
The HTV-2 glider was to fly 4,800 miles (7,700 km) across the Pacific to Kwajalein at Mach 20. [12] The HTV-2 was boosted by a Minotaur IV Lite rocket launched from Vandenberg Air Force Base , California; the glider was carried inside the nose of the Minotaur IV Lite rocket into outer space with a launch altitude of 100 miles (160 km).
The first manufactured object to achieve hypersonic flight was the two-stage Bumper rocket, consisting of a WAC Corporal second stage set on top of a V-2 first stage. In February 1949, at White Sands, the rocket reached a speed of 8,290 km/h (5,150 mph), or about Mach 6.7. [2]
The Pegasus rocket booster separated from its B-52 carrier at 40,000 feet and its solid rocket took the combination to Mach 10 at 110,000 feet. [9] The X-43A split away at Mach 9.8 and the engine was started at Mach 9.65 for 10–12 seconds with thrust approximately equal to drag, and then glided to the Pacific Ocean after 14 minutes. [ 9 ]
