Lights over Jackson, Tennessee.I was at work at scrap yard at Jackson Tennessee. We had two garbage trucks from Waste Management that we were taking the garbage compartment off of the back of the truck to cut up and process for scrap. We had finished the first one and were walking to the second one, when what at first I thought was a row of ducks or geese caught my eye. I thought that I had never seen birds flying that high before. Then I noticed they werent birds but lights that were wagging up and down or in a circle pattern. There were twelve or fourteen of them in a single line and they kind of faded out from view then reappeared. There were three other people with me and I pointed up and hollered HEY! LOOK!. I could tell they were all attached to something but I could not tell what the shape of it was but it was as big as a couple of train rail cars. As i was pointing at it, it faded from view again, and I didn't see it again.
