i thought when something breaks the sound barrier, it can produce an ear-shattering sound but they're good? i guess the information i have in my brain is wrong.
Not necessarily wrong.. it depends on where he actually broke the sound barrier and the relative position of the party to that point.
If you're behind that point you only get the secondary noise from the shockwave, not the noise from the schockwave itself.
Still loud, but don't forget the stupid bird was setting off quite an impressive amount of loud fireworks itself...
It'd have been one Bang amongst many..
