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]

He was the fastest flying man alive and would hold the record until 1961, when the X-15 reached four times the speed of sound (Mach 4). Having been flown 12 times before Apt's flight, it was known ...
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.

The subsonic speed range is that range of speeds within which, all of the airflow over an aircraft is less than Mach 1. The critical Mach number (Mcrit) is lowest free stream Mach number at which airflow over any part of the aircraft first reaches Mach 1. So the subsonic speed range includes all speeds that are less than Mcrit.
