Yes I know. I thought I mentioned in one of my posts that I was a keyboard player and know what these sounds are and I can make them for instance with a Moog synthesizer. The big thing though, is the wattage it would take to make sounds that big. The only way you could cover a whole country like Costa Rica would be HAARP I would think. There is no PA system that could produce that big of sound that would cover a whole country.
Something else I noticed today, is it seems we have copy cats now. Listen to this video of Czech on the 12th-16th.
Now listen to this one from Russia on the 18th.
This first minute of the Russia one is EXACTLY the same as the Czech one.
