No, if you fly an aircraft above water, at super sonic speeds, you can see this effect, and it STAYS with the aircraft till it slows below mach 1, or it gets far away from the water.
I think its the moisture in the air. I've seen a video of an F-14 doing it.
The Bubble stays around the aircraft for as long as it flies over mach 1.
So the photographer probably had a whole minute in which to take pictures.
