Ok, AFAIK the SR-71 was able to go mach 3+, but not hypersonic, so I think I am messing up somewhere, but I don't know where.
-source-
So 1.6 miles/second x 60 seconds/minute x 60 minutes/hour = 5760mph.
Put that into Nasa's mach calculator at 80,000ft, and you get mach 8.722.
So, am I wrong, is the pilot wrong, or is the plane hypersonic?
