Project 10073 Record — Mt. Clemens, Michigan, 9 January 1967

This document details the investigation into a UFO sighting reported on 9 January 1967, in Mt. Clemens, Michigan, by two brothers, Grant and Dan Jaroslaw. The witnesses reported observing a dark gray, disk-shaped object hovering at a low altitude for approximately ten minutes before moving rapidly to the southeast. The boys claimed to have taken photographs of the object. Major R.W. Nyls of the 1st Combat Support Group at Selfridge Air Force Base conducted the investigation. Throughout the process, the family was described as reluctant to share the original prints, which raised suspicions of a hoax. Major Nyls noted inconsistencies in the boys' accounts, specifically regarding the timing of the photographs, as the numbering on the prints suggested that a photograph of a helicopter was taken before the object, contradicting the boys' claim that the helicopter appeared five minutes after the object had left. Major Nyls also noted a coarser texture on the helicopter photograph and suspected the object in the other photos might have been a model suspended from a pipe structure in the family's yard. Despite attempts to obtain the original prints for formal analysis by the Foreign Technology Division (FTD), the family refused to cooperate fully. Dr. J. Allen Hynek, a scientific advisor to Project Blue Book, was contacted regarding the case after he was quoted in the press as saying the photographs appeared authentic; he later clarified that he had been misquoted. Ultimately, the Air Force concluded that there was insufficient data for a definitive evaluation because the original photographs were never made available for analysis.
