Ah, I was hoping to see the discontinuity of the sound wave forming as it steepens.

Still cool!

Very cool. It's fun to see what triggers the "bang" effect when you are at supersonic speeds and in "Moving Source" mode.

Notice that the default is "wind mode", which is why it appears that the waves are moving faster than the speed of sound.

Small error. The pulse "rate" should be called pulse interval (more/right on the slider = fewer pulses per time, which would be a lower rare.)

If you want to see a supersonic boom, switch to moving target at just over mach 1, and turn the sound on. And you can see you can still get much of the effect from a non-supersonic flypast. So hearing a "boom" does not necessarily mean something is supersonic.

I was able to get 13.5 waves/sec, though not consistently.

at flight that I had bunch of years ago i peeked into printed out manuscript that guy sitting next to me was reading. it was something about "explosive formation of underwater shock wave and how it influences metal hulls". might have included something like DOD and MIL at footer.

later I tried to google some of the phrases that I remembered, but couldn't find anything
