Thinking about DUMBs gives me the creeps let alone if/ when they're "officially" revealed to the public.
Last summer I was up around 1:30-2am in Michigan and there was a massive (and I mean massive) boom that I can only think of as being an explosion. It was so loud that it shook my entire house -- I don't scare easily but man was I freaked out. Ive never heard such a loud boom before. Definitely Creeped me out more thinking that there's a DUMB near and below me.
Ive heard sonic booms out over Lake Superior when I was at Tech in the 80s and K.I. Sawyer was still open. They are loud and they do shake the ground even from miles away. But its illegal to go supersonic over the continental US land mass unless they have a damn good reason.
Even if a jet went supersonic at 30k feet, then it wouldn't "shake the ground," would it?
I'm beginning to lean toward underground explosion of some sort.
