Me and a friend were walking to our car. we were making a run for snacks so we can come back and record music. i stopped to observe the beautiful night sky, which was quite clear this night, and noticed a particularly bright plane. i stopped my friend and pointed out that this plane was flying strangely. it did not blink like a plane, nor did i hear anything. it was difficult to determine size or shape as it was nothing but a slightly hazy orb of light. it had a light blue hue, and was the brightness of three north stars, or a very close plane on a clear night. the light was the sort to glow rather than beam, so it's dimensions were shrouded. the treeline was low, and the way it'd fly above and below the treeline made us think it was a drone; however, this did not fly like any drone i've seen in life or video. it's motion was simply too fast and controllable for any drone the public has seen. it would hover for a couple seconds then pick up speed and curve down and to the right, then move to the left, up and back down, below the treeline for a time, then back up, always turning and varying its speed. it was as though someone was standing in the pitch dark with a round glow stick and moving their arm about; the motion, brightness and distance of the object added up to something so unnatural to all known flying objects. me and my friend were surprised and knew it was nothing normal. it dipped below the treeline for a time and we decided to leave. we never saw it again.
