Circular UFO seen in the Atlantic in 1955

Summary

In April 1955, an observer in the Atlantic reported a circular object with a blue-silver color, larger than the moon. The sighting was visual and lasted an unspecified time. The report, part of Project 10073, does not include photos. Analysts considered it could be a balloon, an aircraft, or an astronomical phenomenon, but there was insufficient data for a definitive evaluation. The report suggests it could be a meteor, though no explanation can be ruled out.

The object appeared suddenly, and its trajectory was not precisely recorded. Despite considering various hypotheses, from aerial objects to natural phenomena, no clear conclusion was reached. This case is an example of how UFO reports from that era were difficult to verify, leading to tentative and sometimes conflicting conclusions.
