UFO flew above us in a "S" shape and flew away at high speedMy brother and I were traveling on a high way at a speed of about 130km/h when we suddenly saw a bright light in an oval shape moving about 200m above the ground. This occurred at night time. The UFO was traveling in a straight line and then suddenly made a strange turn in the shape of a "S" and then flew away at tremendous speed till it disappeared.
