🇺🇸 USAF — Project Blue Book
A civilian observer in Bert, Michigan, spotted a bright red oblong object on September 3, 1956. The object appeared at 12,000 feet and drifted northward, maintaining a steady course for six minutes before gradually fading from view. The duration, shape, and manner of disappearance led investigators to consider it likely caused by an aircraft. There were no photographs or interceptions, and weather conditions were clear. Although not definitively identified, the description fit an aircraft better than a balloon or astronomical phenomenon.
The report classifies the sighting as probably caused by an aircraft, ruling out other explanations like balloons or astronomical events. The observer noted no unusual activity, and no interception attempts were made. Despite the lack of confirmatory visual evidence, the available data suggest a conventional explanation. This case, like many others, highlights the difficulty of distinguishing between unidentified objects and conventional explanations based on limited observations.
