I came here looking for stuff about strange sounds and aerial sounds around Western KY and Southern IN. I live in the western third of the state, and for the last month, maybe two, we have been hearing what we believed were the strip mines blasting. But what had us confused is that the strip mines had been closed. Then a couple of nights ago, I and my wife, heard what sounded like an extremely loud jet engine flying overhead at a low altitude. How low, I have no idea. But in the last couple of days, we've been reading about people in Owensboro, KY also hearing these "booms" and also have learned they have been featured on the local news out of Evansville, IN. I kind of thought, with the proximity of Fort Campbell, Fort Knox, and some Forts over in IL, I figured we must be hearing sonic booms. But I know it is illegal for military planes to create sonic booms over populated areas. So what gives? I know this is the first post, if it goes through. Hopefully someone will have further information. I'll be checking back.
