Project 10073 Record — Sighting near Lachine, Michigan, 11 September 1967

This document contains a collection of records related to a UFO sighting reported by a civilian near Lachine, Michigan, on the night of 11 or 12 September 1967. The primary witness, a 20-year-old male, reported observing a single, solid, grey metallic disc-shaped object with runners on the bottom for approximately 40 minutes. The witness described the object as initially appearing like a star, but later hovering overhead and emitting a soft, fluorescent-type beam of light. The witness and his companion attempted to signal the object using flashlights and a spotlight, noting that the object responded with a series of flashes before departing at a high rate of speed. The report includes detailed questionnaires completed by the witness, sketches of the object's motion and appearance, and internal Air Force correspondence regarding the investigation. Air Force officials noted several inconsistencies in the witness's account, particularly regarding the timing and the specific sequence of events. The Foreign Technology Division (FTD) attempted to verify the location and details of the sighting, noting that 'Lachine, Michigan' could not be found in standard maps, leading investigators to suspect the observers were near the Alpena airport. Despite requests for further information, including the identity of the police department and radar facility the observers claimed to have contacted, the requested data was never returned. Consequently, the case was officially categorized as 'Insufficient Data for Evaluation.' The file also notes that the report was forwarded to the University of Colorado for inclusion in their broader study of unidentified aerial phenomena, and that Dr. J. Allen Hynek was requested to comment on the case, though he failed to provide additional information by the time the file was closed in 1968.
