Sightings at Grand Haven and Holland, Michigan, February 27, 1967

This report details an investigation conducted by William T. Powers into a series of UFO sightings reported in Ottawa County, Michigan, on February 27, 1967. Following news and telephoned reports to the Dearborn Observatory, an investigation was initiated involving interviews with three primary parties and site visits to obtain angle measurements. The investigation also consulted personnel at Grand Haven Airport and FAA controllers at Muskegon County Airport to rule out conventional aircraft. The report provides a detailed timetable of events, noting that multiple witnesses observed bright, round objects with red and green lights. While some sightings were attributed to the planet Venus, others remained unidentified. The investigator concludes that while the objects' appearance is similar to aircraft landing lights, no specific flights could be identified to confirm this. The report emphasizes that the observed rapid motions and sudden appearances are likely attributable to human perception and the limitations of the observers' viewing conditions, such as the use of binoculars on a patrol car roof. Ultimately, the investigator states that it is impossible to conclude whether the objects were conventional or unconventional.
