I think you're alone in not seeing a problem with it. And... we're just paying attention to what a sonic boom [u]is[/u] (answer: shockwave, which is also the dangerous thing about explosions). Or, importantly, a deafening noise right next to you. Guns damage hearing for a reason.

Hopefully not 747-level thrust, at least. :/
