Disc / Saucer UFO Sighting in Ten Mile, Tennessee — Report #2423

I was burning some trash when my dog starts barking and runs around to the other side of the house. I follow her and when I get there I look up slightly above some trees in a field that borders our yard when suddenly I see two quite large gray colored disk shaped craft flying thru the air. One was in front of the other. The one in front was flying somewhat lower than the one in the back. They had no windows or doors or lights or markings that I could see. There was no exhaust plumes. They emitted no sound. The most amazing fact to me was how something so big was moving so slow meaning the physics and technology required to keep these things airborne without any visual evidence of them burning some kind of fossil fuel would have to be so advanced that they would be off the charts. They flew across that field then across the road on to the spot where they were then above the woods. They flew on over the woods until I couldn't see them no more past the treeline.
