Craft spotted very distantly NNE of Lake Mozongo outside of Maryville. The craft consisted of 2 vertical parallel light formations with 4 lights in each row and the lowest light on the bottom left track was exceptionially. From the bright light there also appeared to be a diagonal tail to the left that flickered as if the bright light sent a signal down that came back. This tail appeared to have at least 4 lights. Floated in the same spot for some time until it was no longer visible due to the strength of the full moon and clear sky.
