Project 10073 Record Card and Associated Correspondence — St. George, Utah, 22 September 1959

This document collection details a UFO sighting reported on September 22, 1959, near St. George, Utah. A civilian doctor and pilot, accompanied by ten other witnesses, observed a constant, bright white light traveling at high speed from East to West. The object was estimated to be at an altitude of 60,000 to 80,000 feet and was described as being the size of a large aircraft. The witnesses initially reported that the object crossed over two multi-engine jet aircraft that were in the same area at the time. The sighting lasted approximately four to five minutes. The Air Force initiated an investigation under Project 10073. Initial reports suggested the object might have been an aircraft anti-collision light. However, subsequent internal correspondence from the Air Technical Intelligence Center (ATIC) questioned this conclusion. Specifically, investigators noted that if the light were as intense as reported, the crews of the two jet aircraft in the area should have seen it. Further analysis indicated that the second jet was trailing the first by five to ten miles, and the object was observed crossing over and above the second jet. Consequently, it was deemed unlikely that the object was observed by the personnel aboard the jets. Despite the investigation, the official conclusion remained that the cause was undetermined, though the report itself was considered reliable.
