In the winter of 1953, a flying saucer was reported to have circled around a B-36 bomber and blinked a light as though signaling. Investigators from ATIC determined the following facts: At 1:13 A.M. on February 6, 1953, the pilot of a B-36 plane bound for Spokane, Washington, was near Rosalia when he sighted a round white light below him, circling and rising at a speed estimated at 150 to 200 knots as it proceeded on a southeast course. The B-36 made a sharp descending turn toward the light, which was in view for a period of three to five minutes, but the pilot could not identify it. At 1 A.M., thirteen minutes before the sighting, the United States Weather Bureau station at Fairchild Air Force Base had released a pibal balloon. Winds aloft at altitudes of 7000 to 10,000 feet were from the northwest with a speed of about fifty knots. Computations showed that the existing winds would have carried the balloon to the southeast, and it would have been over Rosalia, which is 12.5 nautical miles southeast of Fairchild Air Force Base, in about fifteen minutes. The plane sighted the unknown near Rosalia thirteen minutes after the launching. The balloon carried white running lights which accounted for the blinking described, and the circling climb of the UFO is typical of a balloon’s course. Thus all the evidence supports ATIC’s conclusion that the UFO was a weather balloon[III-2]. A similar sighting had occurred near Hamilton Air Force Base, California, on the afternoon of August 3, 1952--toward the end of the summer’s saucer scare (_Chapter_ VII)--when several pairs of saucers supposedly engaged in dramatic duels in full view of the base. Ample evidence supports the Air Force conclusion that the UFOs were balloons. The two objects were first seen at 4:15 P.M. Ground observers at the Air Force base, with the aid of binoculars, described them as silver in color, circular in shape, 60 to 100 feet in diameter, and traveling from east to west at an estimated speed of 400 to 450 miles an hour. One object was at about 12,000 feet, the other at about 18,000 feet; as they moved to the west a distance of about fifteen miles, passing over the heads of the observers (but not circling the base), the higher object dived to about the level of the lower, and they bobbed about each other for about an hour and a quarter. Toward the end of this period they were visible only intermittently because they were seen against the sun. Three additional pairs of objects (a total of eight) came into view fifteen to twenty miles west of the observers and, buffeted by the winds, appeared to carry on a dogfight; momentarily they appeared in a “diamond” formation extending over an area of about four miles. Since the witnesses were looking into the sun at objects fifteen or twenty miles away, they found it difficult to follow the course of any one for any length of time.
