UFO Wisconsin 1957 identified as balloon

Summary

A 1957 report describes a sighting in Wisconsin where an object resembling a star with an elongated shape was observed. Its flat top and color changes through fog, snow, or clouds led to the conclusion that it was likely a balloon. Several similar reports noted that astronomical bodies can appear to move and change color under adverse atmospheric conditions. Although no photos were taken, the report ruled out an aircraft or astronomical phenomenon, concluding the object was a balloon.

The document, part of project 10073, was reviewed by multiple officers and classified as likely a balloon. The observation was brief and could not be precisely evaluated, but the context of the era and atmospheric conditions supported the identification. This case reflects how UFO reports were often resolved with conventional explanations, even when the object's appearance initially raised doubts.
