We have a B-17 that comes to our local airport down the road pretty much every year ( Commemorative Air Force ). When they do the engine run-ups prior to flight, you can hear it from my house like it was just across the street, and I’m at least 5 miles away. Nothing sounds like that.
Hahaha, my wife tolerates this. behavior...:)
Until 17 years ago, it was named the “Confederate Air Force.”
