UFO sighted near a lake in Wisconsin in 1957

Summary

A civilian police officer reported a round, yellowish object with flashing light hovering over Lake Kosh in Konoma, Wisconsin, in December 1957. The observation lasted 30 minutes, and the object remained stationary. Although no photos or radar were used, weather data indicated that a balloon released in La Crosse could have reached the area around the time of the sighting. Winds of 40-45 mph and a distance of 110 miles support this theory.

The official conclusion suggests the object was probably a balloon, which fits the observed behavior and weather conditions. Despite the unusual flashing light, there was no military activity or interception, and the report mentions no other explanations. This case, like many from the era, reflects the difficulty in distinguishing between conventional objects and unexplained phenomena, especially in hazy conditions with isolated observers.
