Determining the fastest aircraft in the world is difficult, because of the wide variety of designs. For example, most high-speed aircraft are unable to take off under their own power, requiring a carrier aircraft. An aircraft is any machine capable of atmospheric flight. ...
The Space Shuttle is arguably the fastest aircraft, reaching speeds of 20,000 to 25,000 miles per hour. However, it is entirely unpowered, relying on residual speed from being in orbit. Also, during the early, high-speed parts of re-entry, it uses that residual speed and friction from aerobraking to maintain altitude, rather than aerodynamic lift. It is unable to take off under its own power, requiring two discardable boosters and a discardable fuel tank to reach orbit. The Space Shuttle Columbia seconds after engine ignition, 1981 (NASA). ...
Gliders are heavier-than-air aircraft primarily intended for un-powered flight. ...
In physics, an orbit is the path that an object makes, around another object, whilst under the influence of a source of centripetal force, such as gravity. ...
In physics, friction is the non-conservative resistive force that occurs when two surfaces travel along each other when forced together. ...
An artists conception of a spacecraft aerobraking Aerobraking is a technique used by spacecraft in which it uses drag within a planetary atmosphere to reduce its velocity relative to the planet. ...
The Boeing X-43A is the fastest air-breathing aircraft, having set a speed record of 11200 km/h (7000 mph), or Mach 9.8, on November 16, 2004. However, it is unmanned, and relies on a carrier aircraft to reach altitude, and a discardable booster rocket to reach the operating speed of its scramjet engine. It is also incapable of landing. It has been suggested that Hyper-X be merged into this article or section. ...
A scramjet (supersonic combustion ramjet) is a variation of a ramjet where combustion of the fuel air mixture occurs at supersonic speeds. ...
The rocket-powered X-15 is the fastest powered, manned aircraft, reaching a top speed of 7,274 km/h on October 3, 1967. However, it is rocket-powered, carrying both fuel and oxidizer. It requires a carrier aircraft to take off. Description Role: Research Aircraft Crew: one, pilot Dimensions Length: 50. ...

1967 (MCMLXVII) was a common year starting on Sunday of the Gregorian calendar. ...
The SR-71 "Blackbird" is usually considered the fastest "regular" aircraft, with a top speed of 2,522 miles per hour. It is a manned aircraft powered by air-breathing engines, and is capable of taking off and landing unassisted. The Lockheed SR-71, unofficially known as the Blackbird, is a long-range, advanced, strategic reconnaissance aircraft developed from the Lockheed A-12 and YF-12A aircraft by Lockheeds Skunk works, which was also responsible for the U-2 and many other advanced aircraft. ...
