UFO shaped like an umbrella seen over Flint in 1956

Summary

In September 1956, a witness in Flint, Michigan, observed an unidentified flying object for one hour that changed shape between a triangle and an umbrella. The object was the size of a baseball, green in color, and had a tail. Although the report mentions the possibility of a balloon, the lack of weather data and vague description led investigators to conclude that there was insufficient information for a definitive evaluation.

The case was considered too incomplete for a precise classification, which was not uncommon for reports from that era. The description of the object and its north-south movement generated some curiosity, but without images or radar data, its nature could not be determined with certainty. This type of report reflects the difficulty of evaluating unconventional aerial phenomena with the resources available in the 1950s.
