My friend and I were outside on her back deck. We were just dancing and fooling around when we looked at the sky and saw something circular looking flying through it very fast. We noticed it because of the lights, they stood out against the dark sky. Right when we saw it, we thought it was a ufo, there's no other explanation for what it could have been. Now here's the details. It had three lights on it, red white and yellow. It was totally silent, however my friend said she heard one beep. It dropped straight down into the trees and we couldn't see it anymore. Then another one flew across the sky, faster than the first one, following the same path. It also went down below the tree line. My friend says she saw a third however I didn't. We were kinda scared and surprised. We ran and told her mom after they all disappeared. We lost sight of them when they lowered into the trees.
