By the way breaking the sound barrier is a figure of speech that was used in the early days to describe the efforts to reach the speed of sound. It actually has nothing to do with the boom which you can hear at any speed above that. The boom is simply the very sudden change of air pressure as the shock wave passes.

Treat it as a joke. I remember back when I was in the AF seeing a pair of F-104's make a straffing run on a building. They hit it with rockets.
Then with the guns. Then passed over it at 50 feet going about 1.3. The rockets and
guns did about the damage you would imagine. The shockwaves simply flattened the building. Whoomp! Nothing left.
The supersonic shockwave from a jet at 25 thousand feet produces a boom
that is painfully annoying and sometimes breaks windows. Up close it is something
else entirely.
This is pretty cool:
