Hello Col. Richard Graham!
Do you know how far you traveled during your flight history in the SR-71?
I tried a calculation using the cruising speed of the plane as Mach 3.1
Mach 1 = 750 mph (for simplicity)
3.1 x 750mph x 765h = 1,778,625 miles of flight
Earth's circumference is about 24,901 miles around.
1,778,625 mi / 24,901 mi = 71 trips around the world over the course of 32 days.
