Project 10073 Record Card and Staff Message — Sighting of 1 May 1964

On May 1, 1964, a civilian construction worker employed by the Burgraf Corporation reported a sighting of an unidentified aerial phenomenon near Utah Hill, approximately 17 miles south of St. George, Utah. The witness, a 25-year-old male, observed the object for one hour and 35 minutes, beginning at 0415Z. He described the object as initially moon-shaped and later changing to a star-shape, with a bright glow surrounding it. The object reportedly moved from a 90-degree elevation to a 30-degree elevation, traveling from the North toward the Northwest, and eventually diminishing to the Northeast with 'left and right tacking movements.' The witness, identified as Mr. Hunt, attempted to document the sighting by taking a single photograph at the end of a roll of film using an Argus C-3 50mm camera with Kodak Plus-X film. Upon development by the base photo lab, the negative showed no object. The Air Force investigation, led by MSGT Fredric J. Haberkern, concluded that the sighting was caused by a weather balloon released from the weather station at McCarren Field in Las Vegas, Nevada. The report was officially closed following this assessment.
