Any planefags on right now? Hearing more than normal amount of aircraft flying low over in the Fort Knox area, but what's really strange is can't see anything. No marker lights or anything. Sounds like they would be about cargo size aircraft. All flying somewhat south to north by the sound.
Thanks. Sounded like 4-5 of them, but couldn't count too well. Train diluted the sound of 1-2.
Thanks to captcha, my post was too late for while it was happening. A bit louder and lower than what we usually hear, but the strange part was seeing absolutely nothing.
