Eh, I've been staying away from jumping on the bandwagon, sure I'll find an explantion for what I've been experiencing over here. But I've been
hearing the rumble too. Sounds exactly like the sound in that video someone put up.
Now I know the sound when the fighter jets are practicing at high altitudes and can recognize that rumble. This is different. It also slightly shakes
my house and goes on for a long time. The day before yesterday, it happened, and i don't know for how long, because I just kept thinking whatever it
was it would go away, and didn't turn my attention to it until it had already been going for quite a while. Unlike the Hum, this is totally outside
and exterior and can be heard audibly, as well as felt.
We live in France, in a very rural area of the mountains, and our neighbors are not that close, so we don't see them often. But if I do, I will ask
them if they have been noticing this.
