No. See https://en.wikipedia.org/wiki/Sonic_boom
The plane is constantly breaking the sound barrier. The boom is what you hear and feel when the shockwave reaches you.
What happens at the speed of sound?
Yes but it won't make a sonic boom.
Bright lights moving at "Mach 2" and no reports of hearing a sonic boom?
what about noise is you're supersonic noise and sound is about a mile back
Explosion or sonic boom. Large object, moving fast, not very aerodynamically optimized.
There is no sonic boom visible or audible in that video.
Is the speed of sound barrier higher too?
how is that supposed to work at 60km and the speed of sound?
