A friend and I were at New Center School in Sevierville. We had just finished walking and decided to swing. We were swinging for about 10 minutes then I spotted a light out of the corner of my eye. I looked up and seen three ball shaped lights just moving slowly in like a perfect triangle formation. I thought it may be a plane but I have never seen a plane like that. One was a darker orange color and the other two were more yellow. I couldn't stop looking at it. It was moving slow then started to disappear. We even sat and waited about thirty minutes to try and see it again but it didn't appear. I first seen the object around 9:45 pm. I also apologize for the second of foul words in the video.
