Back in the 1960s (!) the military would fly supersonic over the town I lived in. I always enjoyed the boom. I would also open the window during a thunderstorm or go sit on the porch because I enjoyed the incredible electric display and the booms.

For good reason. You cannot train for hedgehopping to avoid radar detection without flying low with firewalled throttles.
The lower the plane flies the fewer people end up hearing the boom. The denser air also requires an absurd amount of fuel to fly through. Commercially uneconomical. Even the military only uses low level supersonic for a last dash to the target.
I am more anti-(manufactured)-war than most, but these sights were the stuff of goosebumps (the good kind).
I'm not sure how the sonic booms of fighter jets compare to passenger planes, though.
