i remember them doing sonicboom testing over our house when i was a kid...
It amazed me.
There was something completely alien about seeing it coming...the shockwave flashing on and off intermittently not a sound.
Then, the thing would zip past, still no sound, but moving faster than you have ever seen anything move.
Then...
BOOM!
Even the guys who hated being in the Navy would jump up and down, pumping their fists, and cheer!
