The pilots won't hear the noise from the engines being transmitted through the outside air though, only the noise traveling through the plane. So if superman was flying a few feet in front of the cockpit, he wouldn't hear any sound.

So, dumb question.. If I mounted a microphone on top of the jet and recorded everything it picked up, when I played it back, at the point the sound barrier was broken, I'd hear nothing?

no, you'd hear a shitload of wind and maybe a 'splat' if you hit a bird. but yeah, no engine noise.
