Rafale supersonic flight

One more for my personal colection of condensation. And...... phi729 is correct.

This kind of vapor cone only occurs at transonic, (and not supersonic), speed. This is the result of the Prandtl-Glauert singularity, a visible phenomenon explained by the combination of fluid mechanics and aerodynamic laws. Not mix up with lift or vortex generated condensations, occurring during high-g maneuvers.

I wasn't aware there were any supersonic corridors in France...Maybe this was somewhere else? Or not actually over M1?

the term "wall of sound" gave sense in this weather
condition

Nice. I havent seen anything of these things going super sonic.
