I heard two rumbling sounds on a sunny clear day TWICE in Europe a few years ago.
was like a rolling thunder across the sky, I know this because I stopped what i was doing and thought wtf is that!
Never heard it since.
Not a cloud in the sky, sunny clear blue sky.
I won't ever forget it, something was up those days.
I assume atmospheric ducting causing the sound to travel the way it did.
Still, something worth remembering.
It was not a metallic sound, but more of a rolling thunder. More of a NATURAL sound than anything. Now I do solar astrophotography so I assumed it was
related to various external events. Never thought anything more of it really. But it certainly was something that I will remember.
