I was driving on I-40 near Crab Orchard, TN when I Sighted UFO in the sky. At first I thought it was a drone, but realized it had a large red tail/trail and a very peculiar appearance. The UFO was black metallic-looking sphere covered in orange octagon-shaped lights. UFO moved in a straight line from my view and disappeared over the tree line of the nearby mountains. mufon cms # 82575
