🇺🇸 USAF — Project Blue Book
In March 1967, a witness in Mount Prospect, Illinois, reported seeing two bright objects moving across the sky. According to the report, the objects were larger than visible stars and separated at different times. The witness described a straight path from east to west, at an elevation of 20 degrees, lasting approximately one minute. Although no photographs or instruments were used, the testimony was passed along by the 45th Air Defense Brigade from Chicago. The observer's reliability was not confirmed, but the report includes detailed weather conditions and wind data at various altitudes.
