I never mentioned what altitude it would do Mach 1.8. The power required to do such things at sea level is stunning. I have been at test sites where planes aproached .9 Mach at 1000 meters. You cannot imagine the sound! Brown noise is widely regarded as a myth, but those who have been near that kind of power have their doubts.
