The objects were estimated to be about two feet in diameter and were flying at an altitude of approximately 200 feet above the ground. The objects moved in a staggered formation, flying south before performing a coordinated turn to the west and then to the north, similar to the movement of a flock of ducks. The witnesses reported that the objects made no sound and left no trail or exhaust. The sighting lasted for approximately fifteen seconds. The report includes weather data from the Duluth weather station, which indicated that a thunderstorm was passing over the area at the time of the sighting, with scattered clouds at 1,500 feet and overcast conditions at 6,500 feet. The observers were driving at approximately 25 miles per hour when they first spotted the objects about a quarter of a city block away. The report is classified as unclassified and includes a road map as an enclosure. The document also contains a summary of the event and a transcript of the teletype message sent to the 31st Air Division and the Air Technical Intelligence Center at Wright-Patterson Air Force Base.
