I completely agree.
Sonic booms.
sparklite2 Beat me by 12 seconds.
BTW I was at a firepower demonstration around 1962 at Eglin AFB.
They demonstrated a sonic boom with an F-104. I came across the sky totally quiet and seemingly not that fast. Then it hit!
I suspect something went wrong as the noise was well above what was necessary to do hearing damage and the shock to the body was real and uncomfortable.
I would bet money that people suffered from it, maybe later in life.
Probably going after a Russian looking too close to London.
I haven't heard one in decades so it's reasonable to assume that anyone who has never heard one would be spooked if one occurred....
Why don't we hear them anymore?
