I think now I'll have someone look up into the Metropolis sky and say, "Look! Is it a bird? Can't be! Birds don't pull contrails!"
Contrails? They're left by water condensing out of engine exhaust, so unless Clark is breathing really fast I'm not sure why they should be there. Bullets, the tips of whips, etc. travel faster than sound and they don't leave them.
Sonic booms are a given, I think, there's no good way to move something man-sized and shaped faster than sound without them.
