New challenge: build a vehicle that can go over 1000mph.
In similar news, I’m collecting v12s so I can build a vehicle that goes over 2000mph.[/quote]
Hypersonic means going Mach 5 and above. In other words, exceeding 3,840 mph or 6,150 km/h.
FYI the fastest manned airbreathing jet aircraft today is the SR-71 Blackbird, which clocks the max speed of Mach 2.883/2,193.2 mph/3,529.6 km/h.
