An unidentified object was spotted by pilot Dr. A. D. Cannon and passenger Einar Neilson aboard a Piper Cub aircraft at 1600 feet AGL, north of Hector Field. It was moving fast to the west above them at about 250-270 mph. Immediately thereafter Air National Guard fighter pilot Lieutenant George F. Gorman plus four others, including two CAA tower controllers, saw a small 6-8-inch round white ball of light with a flat, no-depth disc-like appearance, blinking off and on at slow speed. Gorman radioed the sighting to the control tower and began pursuit at 9:07 p.m.

Cannon and Neilson landed, went up into airport tower and with binoculars watched Lieutenant Gorman attempt to chase the light in his F-51 fighter. Gorman's closest approach was less than 500 feet distance on his first pass at about 5,000 feet. Gorman then climbed to 14,000 feet but stalled out, unable to intercept the light at about 16,000 feet. The light made evasive and aggressive maneuvers, such as seeming to try to ram the F-51, and outperformed the F-51 at a top speed 600+ mph. The light dropped to 11,000 feet. Gorman attempted to dive on it. The light then pulled up, and rose vertically until it disappeared.

One white saucer, about 6 inches across, was observed by five male military witnesses with binoculars, typical age 25, in a warplane for 27 minutes (George F Gorman). No sound was heard.

Ruppelt's account:

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.

In the file on the Gorman Incident I found an old memo reporting the meeting that was held upon the ATIC team's return from Fargo. The memo concluded that some weird things were taking place.

The historians of the UFO agree. Donald Keyhoe, a retired Marine Corps major and a professional writer, author of The Flying Saucers Are Real and Flying Saucers from Outer Space, needles the Air Force about the Gorman Incident, pointing out how, after feebly hinting that the light could have been a lighted weather balloon, they dropped it like a hot UFO. Some person by the name of Wilkins, in an equally authoritative book, says that the Gorman Incident "stumped" the Air Force. Other assorted historians point out that normally the UFO's are peaceful, Gorman and Mantell just got too inquisitive, "they" just weren't ready to be observed closely. If the Air Force hadn't slapped down the security lid, these writers might not have reached this conclusion. There have been other and more lurid "duels of death."

Gorman fought a lighted balloon... An analysis of the sighting by the Air Weather Service sent to ATIC in a letter dated January 24, 1949, proved it. The radioactive F-51 was decontaminated by a memo from a Wright Field laboratory explaining that a recently flown airplane will be more radioactive than one that has been on the ground for several days. An airplane at 20,000 to 30,000 feet picks up more cosmic rays than one shielded by the earth's ever present haze.
