UFO seen at Thule, Greenland in 1960

Summary

In 1960, an observer at the Thule base in Greenland recorded a comet-like object that appeared suddenly and disappeared to the west. The observation was brief, with a limited duration and an estimated elevation of less than 10 degrees. Although several explanations were considered, such as balloons, meteors, or astronomical phenomena, no definitive conclusion was reached. The report highlights the lack of sufficient data to evaluate the nature of the object with certainty.

The document is part of a military file with codes and categories that reflect the confusion and need to analyze multiple hypotheses. Despite the limitations, the record shows how observers tried to classify unidentified phenomena in a context of aerial and space surveillance. The ambiguity of the case makes it an interesting example of the challenges faced by UFO researchers at that time.
