Recently I was watching on Netflix on my computer a documentary and I believe it was called The Third Reich's Tunnels. It showed tunnels that were built in underground Germany. It was absolutely fascinating. It was fine tuned to a t. I am a firm believer that the gov. is and have been following Germany's World Order

If you can see those tunnels, you could see easily how all of that clearing out of underground could cause incredible booms and noises that we hear.

I am in FL and have only heard large booms once or twice. I would doubt if this state would be a model for this work due the sea level here but who knows.

Anyway, when I was watching the documentary, it seemed as if a light came on and things make sense in this respect.

I will double check the name of the film and be back in case anyone is interested.
