Witnesses were walking when they observed a peculiar reddish light. They thought at first that the light was a shooting star but it left no streak. It appeared again and they thought it was a plane flying at very night high altitude. Then a number of intermittant flashes were observed for three minutes. After observing the abrupt darts of light and hearing no hum of motors they concluded that it was definitely not a plane. as the maneuvers appeared too abrupt.
