An "Air Speed Record" refers to the fastest speed achieved by an aircraft over a specific distance or time. These records are officially recognized by organizations like the Fédération Aéronautique Internationale (FAI), which sets the rules and standards for measuring speed. Records can be set by various types of aircraft, including commercial jets, military planes, and experimental vehicles. The current air speed record for a manned aircraft is held by the North American X-15, which reached a speed of 4,520 miles per hour (7,274 kilometers per hour) in 1967. Unmanned aircraft, such as drones, also compete for speed records, showcasing advancements in aviation technology and engineering.
