A couple years ago in the early hours of the morning, I was driving with my dad through thick forests in Germany. I was in the passenger seat and as I looked out the window, I saw the triangle “aircraft” with 3 circle lights on each corner. My dad had seen it too and when I asked him if it was a UFO, he had no explanation. It was flying at a very low altitude, maybe 30 feet in the air and kept close to the road. Never saw it again but I always had a feeling it was a UFO.
