Red triangular UFO over Greenland in 1953

Summary

A weather observer in Greenland, using a theodolite, sighted an unidentified object in June 1953. The incident occurred when a 100-gram weather balloon burst, and the observer claimed the UFO had destroyed it. The object was described as triangular, red, and rotating, hovering at around 16,000 feet for 15 seconds before rapidly ascending northwest without a trail, disappearing after five minutes. The only physical evidence was the visual observation, and weather reports indicated normal conditions, increasing uncertainty about the phenomenon's nature.

The official evaluation suggested it could have been an optical illusion or a theodolite parallax, but the observer's meteorological experience added credibility. The UFO didn't behave like a typical weather balloon or known atmospheric phenomenon, making it an intriguing case in declassified UFO files.
