"Some people found the flyover unnerving; many called 911, and one woman was described as panicked by the sound and sight of a fighter jet over the city."
"many called 911"
The only reason to have called 911 would have been to ask for an encore.
We occasionally have two F-15s do a flyover of Lake James, NC where I live. By the time you hear them, they're not where you here the exhaust. Now we look about a mile further past where we hear them.
The last time, I call a friend who is in the AF and asked him if he talk to the base commander requesting more fly-bys over Lake James.
