F-22 Raptor performing a Prandtl-Glauert singularity

I love the fact that your video info accurately describes the condensation, and isn't just "OMG SEE THIS SONIC BOOM".

@ehushagen yeah man, haha

thanks for clearin things up

i thought F-22s were not authorized to achieve supersonic speeds during airshows ?

[getlow1985]

@enzo321 He is not, this video is just showing the vapor. If he were to go mach 1 you would see the jet quite a while before you hear a boom.

@enzo321 No, and this F-22 is not supersonic. The Prandtl-Glauert singularity cloud ("cotton ball") is not a result of the aircraft exceeding the local speed of sound. It is the result of the expansion of the water vapor (in the air) around the aircraft.

@AIM9XSW Prandtl Glauert singularity is the result of the expansion of the water vapor, the expansion of the water vapor is the result of the difference of presure between the plane and the enviroment, and that's the result of the transonic speed of the plane
