I wonder if it does the same thing coming back to trans sonic zone or the sub sonic zone?

I've never seen anything about a Vapor Cone due to transition from supersonic to subsonic speed, but according to the Wikipedia page(http://en.wikipedia.org/wiki/Vapor_cone) they occur at "transsonic" speeds, so it's entirely possible that one forms in reverse upon the transition.

The effect's even more impressive in video. http://www.youtube.com/watch?v=-1ywUmBpVGY
