What is the fastest speed a human has flown in a plane?

The winner of our top 10 – the X-15! Number 1: North American X-15 This aircraft has the current world record for the fastest manned aircraft. Its maximum speed was Mach 6.70 (about 7,200 km/h) which it attained on the 3rd of October 1967 thanks to its pilot William J. “Pete” Knight.



The record for the fastest speed ever achieved by a human in a manned aircraft is Mach 6.7 (approx. 4,520 mph or 7,274 km/h). This record was set on October 3, 1967, by pilot William J. "Pete" Knight flying the North American X-15, a rocket-powered research aircraft. The X-15 was not a traditional "plane" in the sense of taking off from a runway; it was carried aloft by a B-52 bomber and "drop-launched" at high altitude. While the X-15 holds the record for rocket-powered planes, the Lockheed SR-71 Blackbird holds the record for the fastest "air-breathing" (jet-powered) manned aircraft, reaching Mach 3.32 (approx. 2,193 mph) in 1976. For a broader comparison, astronauts in the Space Shuttle or Apollo capsules reached speeds exceeding 17,500 mph during re-entry, but in the specific category of "flying an airplane," Pete Knight’s 1967 flight in the X-15 remains the benchmark for human speed.

Mach 10 speed has never been achieved by a manned aircraft, though, so it has never been tested. Mach 10 has, however, been achieved by a spacecraft - on November 16, 2004, NASA launched the X-43A, an air-breathing hypersonic vehicle, and was able to reach real Mach 10 while being pushed into the atmosphere.

Absolute World Records are for a given distance or elapsed time, independent of Category, Group, or Class. The current holder of the Outright World Land Speed Record is ThrustSSC driven by Andy Green, a twin turbofan jet-powered car which achieved 763.035 mph - 1227.985 km/h - over one mile in October 1997.

The final flight of the small X-43A research aircraft is targeted to sustain a speed of up to Mach 10, or 10 times the speed of sound (about 7,000 mph), powered by a revolutionary airframe-integrated supersonic-combustion ramjet or 'scramjet' engine.

In conclusion, while certain experimental aircraft have achieved speeds surpassing 1000 mph, commercial planes are not currently capable of reaching such velocities. The interplay between engine power, aerodynamics, weight, and altitude all contribute to an aircraft's top speed.

Current rules prohibit commercial airplanes from flying at supersonic speeds over land because of the noise levels associated with sonic booms and the negative impacts to humans and animals.
