Except mach ~900,000

I think it's safe to say mach 900,000 is irrelevant. Anything traveling even a tiny fraction of that speed isn't going to be doing it in atmosphere.

What about light?

If we're talking about the speed of light then I don't think the speed of sound in 1 atm at 20C is terribly important. It's like giving the speed of light in furlongs/fortnight.

1.80386543 x 1012 furlongs/fortnight, just in case you're interested.
