So basicly most of my thoughts are invalid because the wave is only supersonic for a very short duration, if at all. Hmm

I was thinking of the two as the same thing, as in looking at the thing go off, then "hearing" the supersonic wave. Yes I've done this myself with thunderstorms. But when dealing with the lightning you get that distinct loud crackle(blast wave) that i would say is supersonic when struck close...

To calculate the distance from a stationary visible object using the speed of sound when dealing with a supersonic blast wave from that object, how would one proceed? Is the standard 340m/s good enough reference? How is the velocity reduction over time and distance? Does all the variables...
