Patrick McDonough was assigned to the 1381st Geodetic Survey Squadron at Malmstrom AFB, MT, in 1966. His job was to properly align the missile silos within the missile field. He reports that one night in September 1966, a disc-shaped UFO raced in and hovered silently at low altitude directly over the site he was at for a few seconds. McDonough and his team were so terrified that they jumped into their truck and left the scene at high speed. At one point, he missed a sharp turn in the road and rolled it. Fortunately, no one was injured.
