Such effects have been seen around my Rover 75, but only in the mornings after a vindaloo.

Looks like the bird that circles round my house and regularly shits on my windows.

Nah, it's a metallic sort of dolphin thing that can float and fart at the same time.

It's not 'breaking the sound barrier'. B2's are not supersonic aircraft. It can do about Mach 0.95 flat out although its usual cruising speed is about the same as a 747. This is 'transsonic', not supersonic.

You can get a Prandtl-Glauert singularity at subsonic velocities under the right conditions (high humidity, high g or large angle of attack).
