HollieSix minutes suddenly sounds like forever.
I did a web search for Mach 32 in MPH, and got three different answers. So...roughly 24,000 mph but nobody knows for sure?

@hollie The problem with Mach numbers is that they vary based on temperature and pressure. Mach 1 at sea level is much slower than Mach 1 at the edge of the atmosphere.
@valthonis Yeah I didn't know that until today! So cool. I had always heard it as a static thing but Greg informs me that's just the number that's usually given for sea level.
