UFO observed in Duluth in 1952

Summary

In July 1952, a railroad worker in Duluth, Minnesota, observed an unusual aerial phenomenon that appeared to zigzag upward. The object, as bright as a star, was seen for 10 to 15 minutes without optical aid. Its zigzagging path and wind direction matched what would be expected from a balloon. Several nearby research facilities were known to use balloons for high-altitude studies, supporting this explanation.

The duration and movement pattern of the object were consistent with wind speeds between 25 and 45 knots. Although other possibilities like aircraft or astronomical phenomena were considered, the conclusion was that it was likely a balloon. This assessment was based on weather data and the local context of balloon research. The official report included no photos or radar data but emphasized the consistency between observed data and typical balloon patterns.
