The X-15 set speed and altitude records in the 1960s, crossing the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The X-15's highest speed, 4,520 miles per hour (7,274 km/h; 2,021 m/s), [ 1 ] was achieved on 3 October 1967, [ 2 ] when William J. Knight flew at Mach 6.7 at an altitude of 102,100 feet ...
Dorothy Levitt, in a 19 kW (26 hp) Napier, at Brooklands, England, in 1908. The FIA does not recognize separate men's and women's land speed records, because the records are set using motorized vehicles, and not muscle-powered vehicles, so the gender of the driver does not matter; however, unofficial women's records have long been claimed, seemingly starting with Dorothy Levitt's 1906 record ...

[ 38 ] [ 39 ] Baumgartner was in free fall for 4 minutes and 19 seconds, a fall time 17 seconds shorter than the record set during mentor Joseph ...
A speed record is a world record for speed by a person, animal, or vehicle. The function of speed record is to record the speed of moving animate objects such as humans, animals or vehicles. The function of speed record is to record the speed of moving animate objects such as humans, animals or vehicles.
While it may have been designed as the fastest propeller-driven aircraft, this goal was never realized due to severe stability problems. [7] This record speed is also inconsistent with data from the National Museum of the United States Air Force, which gives a top speed of "only" 840 km/h (520 mph; 450 kn) or Mach 0.70.
