Also known as the "blue angels" and "thunderbirds" in the USA, they are most fighter jets. Realistically, a stunt plane is just a tool to wow the crowd with pilot skill. Even combat aircraft perform most of their missions subsonically, the supersonic capability is just for dash or intercept, not super-manuvering like hard turning.

Would be horrible to watch; it would cover probably 5nm laterally and 50,000' vertically to perform a simple loop at reasonable G-loading.
Airshow crowds don't know too much about airplanes, passing the speed of sound by itself is fun enough, we have fighter jets that approach but never breach. You ears will bleed if the plane is either too close to the ground or going any faster.
The meaning of life is curiosity; we were put on this planet to explore opportunities.
