Your math is good. Great explanation, but its not the time to circle that we are calling into question. It's the 6089.656 mile/hour (Mach 8) number. The SR-71 was fast, but not that fast. Let's say it can get pretty close to Mach 4...then its like 8 hours to circle the earth if we just double the time for half the speed according to the math where you already took into account altitude.
I'm at ERAU by the way...Prescott campus (the one I'm sure you applied to since you are in PHX). You aren't missing much here, lol.
