Project 10073 Record Card and Related Correspondence — Heber City, Utah, May 1964

This document collection details a UFO sighting report from May 17, 1964, near Heber City, Utah. The primary report was received by the Security & Law Enforcement Division at Hill Air Force Base. The witness, a 19-year-old truck driver, reported observing a navy grey, round, and somewhat flat object, approximately the size of a railroad boxcar, circling a mountain at an elevation of 1,000 feet. The witness noted that the object's edges glowed as if coated in phosphorus and that it emitted a sound similar to a jet engine starting. The object eventually rose to 1,500 feet, moved over the mountain, and disappeared. A local weather observer, Linsey Crook, confirmed that the weather conditions at the time were clear with high scattered clouds and a southwest wind. Despite the detailed account, the Air Force was unable to locate the witness for further questioning. Consequently, the Foreign Technology Division at Wright-Patterson Air Force Base determined that the information was insufficient for a formal evaluation. The file includes a record card, internal correspondence between Hill AFB and the Foreign Technology Division, and a letter to the witness (which appears to have been misdirected or confused with another case involving Echo II). The case was ultimately closed due to a lack of data.
