i am not air nautical engineer
thats usually what happens when they break sound barrier
they i think leave the compressed air behind...

It is water. The plane causes a disturbance in air pressure and temperature. The air suddenly cannot hold as much water, so it assembles into visible mist. The name? well there are probably several. Condensation?

What is that cloud around the aircraft? Is there a name for that phenomena?My Vietnam pilot buddy told me it's called 'Breakout'. It's caused by going supersonic. There are many photos of this floating around. Somewhere in my files, I have a video of it happening from the deck of a carrier.

I think it's called a *vapor cone*

The explanation in response No. 6 is pretty good. The airplane is not actually going supersonic - at least, not overall. However, local flow around parts of the airplane can be supersonic or near supersonic when overall aircraft velocity is as low as 70% of the speed of sound in more or less one-g flight, and even lower when accelerating the air a lot in high-lift conditions.

I have always referred to it as the shock cone. It occurs just before the aircraft goes supersonic (when the humidity is high enough). It mostly disappears when the aircraft goes through the Mach, although you can still see remnants of it further back on the wing. It is caused by a decrease in pressure behind the forming shock wave. You can get it on the top of the wing (positive Gs)by pulling enough G's to decrease the pressure. The more humid it is the lower the required G's or the more pronounced the effect is at higher G's.

it's moisture in the air that is knocked into a mist by the shock wave.
