And its not economically cost effective. Doubling your speed means that
your flight regeime is going to be at least ten times more severe, while
you reduce your flight time to the furthest point on earth from 45
minutes at suborbital trajectory to 22.5 minutes at mach 50. I'm not
sure that anyone would pay ten times as much or more for only 22 extra
