What are some science fiction portrayals of supersonic travel that have become reality?

... supersonic cavity reaches Mach 2. The Mach number represents the ratio of the fluid velocity and the speed of sound. Once the Mach number is calculated to ... This contribution is small for mildly supersonic cases but large for high Mach number accretion. For accretion flow with ℳ∞ ≥ 5, the overall accretion ... At Mach 0.65, u is 65% of the speed of sound (subsonic), and, at Mach 1.35, u is 35% faster than the speed of sound (supersonic). An F/A-18 Hornet creating a ... of igniting and sustaining the supersonic combustion of hydrocarbon fuels in a Mach 8 flight-candidate scramjet engine. This will be achieved through the ...
