Hunting in the Shawnee at a place called Oakwood Bottoms. 3am in the tent. Heard an odd, electric sound, more of a hum than anything, coming from the east across the bluffs. Perfectly star-lit night with a nearly 3/4 moon and great visibility. As it got closer, it was making a throbbing sound. The hum would get soft and then get loud very rhythmically. Not an engine. Oddly, it seemed to pass straight overhead, but neither my hunting buddy or me could see it blot out any stars. It was passing really slowly based on the sound, but whatever it was, it didn't blacken the sky though it seemed like it was only a few hundred feet up. Oddest thing I've ever heard. Perhaps it was a stealth helicopter or something, but the throbbing sound didn't seem right.
