It was night. I was at the local football match eating my burger, sitting on a bench when I saw a strong light in the sky. The night sky was clear, no clouds. I first thought it was a helicopter or a plane, but a second later I changed my mind because it was so quiet I couldn't hear it and it was to bright for a helicopter or a plane. First it was going in a straight line (as a plane or helicopter, that's why I first thought it was one of these) but then it suddenly stopped in mid-air, went up in almost straight line, stopped for a second, went down in almost straight line and as it was going down it started accelerating in the direction it was going first (straight line). Then it suddenly stopped and disappeared. Before it disappeared it flashed very bright in a yellow and white color. All this also have also seen my friend that was sitting next to me. After it happened I looked at him and he was as surprised as I was.
