Project 10073 Record Card and Correspondence — Hamilton, Ontario, April 1958

This document collection details a UFO sighting report filed by a civilian in Hamilton, Ontario, Canada, on April 18, 1958. The witness, a machinist for the Fuller Brush Company, was driving on Highway 24 at approximately 9:30 p.m. when he observed a bright, fire-like object. He described the object as a 'ball of fire' with a 'red glowing space in the head' and a blue-white color, trailing white smoke. The object appeared to travel at 'meteor speed' at a 60-degree angle toward his vehicle before landing behind a small woods about one mile away. The witness reported the event to the Royal Canadian Mounted Police, the Royal Canadian Air Force, and the Provincial Police, but received no satisfactory explanation. He subsequently wrote to the U.S. Naval Research Laboratory after reading an article in Life magazine, seeking clarification. The U.S. Naval Research Laboratory responded on May 6, 1958, suggesting the object was likely a meteor or potentially related to the re-entry of Sputnik II, which had disintegrated on April 13, 1958. The correspondence was forwarded to the Air Technical Intelligence Center (ATIC) in Dayton, Ohio. ATIC officials reviewed the report and concluded that the witness's detailed description—specifically the 'red glowing space' and the intense light—were characteristic of a 'true bolide' or fireball. The file includes the original Project 10073 record card, the witness's handwritten letter and sketches of the incident, and the official responses from U.S. military and research authorities.
