Some startling UFOs have been produced by reflections from an object that the witness was not able to see or did not recognize. One night in the spring of 1961 an amateur astronomer reported that a huge cigar-shaped flying saucer was hovering in the sky several thousand feet above the Harvard College Observatory. Investigation showed that the “UFO” was a reflection from a small oblong insulator on an electric wire strung between two buildings. Faintly illuminated from below by the lights from the unshaded windows, it seemed to be an immense and brilliantly glowing object high in the sky. The witness at first refused to believe that he could so mistake the evidence of his own eyes. Next morning, however, he returned to the scene and was able to see that what had appeared the night before to be a giant spaceship was only a small insulator a few feet above his head. The bright sun reflected at a particular time from an object invisible to the observer often produces a puzzling phenomenon, such as the flying saucer reported from Danby, California, early in October 1958. About 4:00 in the afternoon on October 2, three prospectors standing near a tungsten mill at Railroad Danby noticed a sudden bright glow in the northwest sky which remained visible for about 2½ hours and then disappeared. When a glow appeared again the following day at the same time and place, the observers tried to identify it by using a small telescope and saw a bright, oblong object hovering above the horizon; it was the color of aluminum, approximately fifteen feet long, five feet high, and about four miles away. Getting into a car, the men drove in the direction of the object and searched the supposed location on foot for several hours, but could find no trace of the UFO. Several days later, realizing that the object reappeared every day at about the same time and place, two of the men decided to investigate further. Studying the object through a pair of powerful binoculars, they could see guy wires coming from it and rods radiating from the guy wires. Remembering that two tall radio antennas used by the highway patrol stood in approximately the same location, the witnesses found the explanation, which Air Force investigators confirmed. The antennas, placed some twenty feet apart, extended about twenty feet above the trees. The cigar-shaped hovering object was a special effect depending on a particular combination of circumstances: only during the first part of October, and only late in the afternoon, did the sun’s rays strike the antenna in such a way that the reflection was visible to an observer at Railroad Danby[XII-1]. _Sundogs in Utah and France_
