🇺🇸 USAF — Project Blue Book
In November 1957, a witness in Oconto, Wisconsin, observed a white object resembling a football in shape and size. The object remained visible for 35 minutes, suggesting a prolonged presence in the sky. Despite the extended observation, no photos were taken and no additional data was recorded to help identify the object with certainty. The lack of detailed information and the absence of an official report in the files led to the conclusion that the data was insufficient for a precise evaluation. The case remains unsolved, adding another mystery to the history of sightings in the region.
