The record should have gone to civilian (former military) pilot Charles Myers, who flew a Delta Dart at 2,485 kilometres per hour (1,544 mph) in 1959, but Cold War pressures dictated that the award go to an active-military pilot.

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]
The sound source has now broken through the sound speed barrier, and is traveling at 1.4 times the speed of sound, c (Mach 1.4). Because the source is moving faster than the sound waves it creates, it actually leads the advancing wavefront. The sound source will pass by a stationary observer before the observer actually hears the sound it creates.
The Mach number is defined as a plane’s speed divided by the speed that sound waves move through the air. To “break the sound barrier” means to fly faster than the speed of sound, with Mach ...
Even earlier, in 1997, the Guinness Book of World Records listed the Republic XF-84H Thunderscreech experimental USAF fighter as the fastest propeller-driven aircraft, with a speed of 1,003 km/h (623 mph; 542 kn) or Mach 0.83. [6] While it may have been designed as the fastest propeller-driven aircraft, this goal was never realized due to ...
Overture, a larger and faster passenger-carrying version of the test jet, is planned to launch in 2029 with a top speed of Mach 1.7, Boom says. That's about twice the speed of current airliners.
At 65,589 feet, Apt beat all previous records speed records, reaching Mach 3 (2,094 miles per hour). He was the fastest flying man alive and would hold the record until 1961, when the X-15 reached ...
However, Concorde's high noise levels around airports, time zone issues, and insufficient speed meant that only a single return trip could be made per day, so the extra speed was not an advantage to the airline other than as a selling feature to its customers. [34] The proposed American SSTs were intended to fly at Mach 3, partly for this reason.
