It was a rather thick document with a black cover and it was printed on legal-sized paper. Stamped across the front were the words TOP SECRET.

It contained the Air Force's analysis of many of the incidents I have told you about plus many similar ones. All of them had come from scientists, pilots, and other equally credible observers, and each one was an unknown.

The document pointed out that the reports hadn't actually started with the Arnold Incident. Belated reports from a weather observer in Richmond, Virginia, who observed a "silver disk" through his theodolite telescope; an F-47 pilot and three pilots in his formation who saw a "silver flying wing," and the English "ghost airplanes" that had been picked up on radar early in 1947 proved this point. Although reports on them were not received until after the Arnold sighting, these incidents all had taken place earlier.

When the estimate was completed, typed, and approved, it started up through channels to higher-command echelons. It drew considerable comment but no one stopped it on its way up.

A matter of days after the Estimate of the Situation was signed, sealed, and sent on its way, the third big sighting of 1948, Volume III of "The Classics," took place. The date was October 1, and the place was Fargo, North Dakota; it was the famous Gorman Incident, in which a pilot fought a "duel of death" with a UFO.

The pilot was George F. Gorman, a twenty-five-year-old second lieutenant in the North Dakota Air National Guard.

It was eight-thirty in the evening and Gorman was coming into Fargo from a cross-country flight. He flew around Fargo for a while and about nine o'clock decided to land. He called the control tower for landing instructions and was told that a Piper Cub was in the area. He saw the Cub below him. All of a sudden what appeared to be the taillight of another airplane passed him on his right. He called the tower and complained but they assured him that no other aircraft except the Cub were in the area. Gorman could still see the light so he decided to find out what it was. He pushed the F-51 over into a turn and cut in toward the light. He could plainly see the Cub outlined against the city lights below, but he could see no outline of a body near the mysterious light. He gave the '51 more power and closed to within a 1,000 yards, close enough to estimate that the light was 6 to 8 inches in diameter, was sharply outlined, and was blinking on and off. Suddenly the light became steady as it apparently put on power; it pulled into a sharp left bank and made a pass at the tower. The light zoomed up with the F-51 in hot pursuit. At 7,000 feet it made a turn. Gorman followed and tried to cut inside the light's turn to get closer to it but he couldn't do it. The light made another turn, and this time the '51 closed on a collision course. The UFO appeared to try to ram the '51, and Gorman had to dive to get out of the way. The UFO passed over the '51's canopy with only a few feet to spare. Again both the F-51 and the object turned and closed on each other head on, and again the pilot had to dive out to prevent a collision. All of a sudden the light began to climb and disappeared.

"I had the distinct impression that its maneuvers were controlled by thought or reason," Gorman later told ATIC investigators.

Four other observers at Fargo partially corroborated his story, an oculist, Dr. A. D. Cannon, the Cub's pilot, and his passenger, Einar Neilson. They saw a light "moving fast," but did not witness all the maneuvers that Gorman reported. Two CAA employees on the ground saw a light move over the field once.

Project Sign investigators rushed to Fargo. They had wired ahead to ground the plane. They wanted to check it over before it flew again. When they arrived, only a matter of hours after the incident, they went over the airplane, from the prop spinner to the rudder trim tab, with a Geiger counter. A chart in the official report shows where every Geiger counter reading was taken. For comparison they took readings on a similar airplane that hadn't been flown for several days. Gorman's airplane was more radioactive. They rushed around, got sworn statements from the tower operators and oculist, and flew back to Dayton.
