The Mantell UFO Incident

Kenneth Arnold's sighting in June 1947 and Roswell had put flying saucers in the news. Around 1:15 p.m. on Wednesday, January 7, 1948, the Kentucky State Highway Patrol called Godman Field at Fort Knox. Residents of Maysville were reporting a strange craft. Circular. About 250 to 300 feet in diameter. Moving westward "at a pretty good clip."

At 1:45 p.m. the tower saw it too. The assistant tower operator was reluctant to "make a flying saucer report." Staff watched through 6 x 50 binoculars and couldn't identify it. Tower operator T/Sgt Quinton A. Blackwell gave the most vivid description: "to me it had the resemblance of an ice cream cone topped with red."

Capt. Gary W. Carter, the operations officer, saw it "round and white," visible through cirrus clouds. The base commander, Col. Guy F. Hix, watched for nearly an hour. He called it "very white" and "about one fourth the size of the full moon."

Four F-51D Mustangs of the 165th Fighter Squadron, Kentucky Air National Guard, were on a ferry flight to Louisville. Their leader was Capt. Thomas Francis Mantell Jr., 25, who had towed gliders on D-Day. Around 2:45 p.m. he radioed. "I see something above and ahead of me and I'm still climbing." A wingman answered. "What the hell are we looking for?"

At 15,000 feet: "It appears to be a metallic object or possible reflections of sun from a metallic object, and it is of tremendous size. I'm still climbing." Then came a line that every version agrees on. "I'm going to 20,000 feet." Mantell had no oxygen equipment. Lt. B. A. Hammond turned back at about 22,000 feet, seeing double. Mantell kept climbing.

Near Franklin, Glenn Mayes heard the plane first. Then he saw a Mustang in a "tight spiraling dive," breaking up at about 2,000 feet. The tail landed a quarter mile away. The wreck struck the W. J. Phillips farm, about 5 miles southwest of Franklin. Mantell's birthplace. His wristwatch had stopped at 3:18 p.m. At Godman, the tower lost sight of the object at 3:50 p.m.

The accident report found that Mantell blacked out from lack of oxygen and the fighter lost a wing in the dive. The wreck was not radioactive. Project Sign first blamed Venus, an answer J. Allen Hynek later rejected. In 1952 Capt. Edward J. Ruppelt of Project Blue Book rebuilt the case from damaged microfilm. According to one account, he called the Venus answer a "masterpiece in the art of weasel wording." His own conclusion was this: "It could have been a balloon. This is the answer I phoned back to the Pentagon." He meant a classified Navy Skyhook.

Vanderbilt astronomer Carl K. Seyfert described "a pear-shaped balloon with cables and a basket attached." Barry Greenwood and Robert G. Todd placed a launch at Camp Ripley, Minnesota, on January 6, 1948. Doubters remain. Lee R. Trail argued that a balloon at 90,000 feet over Franklin would have appeared about 9 degrees above the horizon from Fort Knox, not 45. In 2023, an army.mil retrospective noted that no document confirms or disproves Skyhook.

Rumours grew. A ray. A body riddled with bullets. The Air Force, Ruppelt and even Donald Keyhoe rejected them, though Keyhoe still promoted the idea that a saucer shot Mantell down. Today a marker stands in Franklin, and Simpson County marks every January 7 as Captain Thomas Mantell Jr. Day.
