On 7 January 1948, staff at Godman Field near Fort Knox, Kentucky, reported a large, bright object in the sky. Mantell, leading a flight of four F-51 Mustangs, was asked to investigate. He climbed after the object, describing it as metallic and huge. He continued above 20,000 feet without oxygen, lost consciousness and crashed, becoming the first well-known death linked to a UFO chase.

The Air Force at first suggested Mantell had chased the planet Venus. Later investigators, including Edward Ruppelt, concluded it was most likely a large Navy Skyhook research balloon, then secret, though some researchers still dispute this.
