  1. The SR-71’s true flat speed is 2198 mph Mach 2,85 I know the higher you go and the temperature changes the speed of sound but the true speed of sound is 767 mph Mach 1 the speed that is used to tell what Mach a jet can it like the Eurofighter 1550 mph using the true flat speed of 767 mph it does Mach 2,0 or the F-22 1498 mph its Mach 1,8 so the SR-71’s true Mach speed is 2,85 for it to hit Mach 3+ at 3 it would need to hit about 2310 mph at 3,3 about 2440 mph and at 3,5 about 2700 mph its speed was only 2198 mph it’s true speed Mach 2,85.
