Maximum air velocity in ambient conditions??

Masters what is the maximum air velocity that can be achieved in ambient condition??
In the throat of sonic nozzle it attains sound velocity. Is it possible to attain more? If yes how?? thanks

With a choked converging/diverging nozzle, after the throat the air will accelerate. That's how a supersonic wind tunnel works: http://en.wikipedia.org/wiki/Supersonic_wind_tunnel
