UFO in Castle Rock, Colorado, 1968

Summary

In January 1968, a witness in Castle Rock, Colorado, reported seeing a UFO shaped like an egg, with a creamy and transparent appearance. According to the report, the object was approximately 50 feet long and 20 feet wide and high, and was rapidly ascending northward. The observation lasted eleven minutes, and although initially considered an unidentified aerial phenomenon, it was later concluded to be a hot air balloon. The report includes details about wind direction and the object's appearance, helping investigators rule out more exotic explanations.

The official Project 10073 report notes that the observer saw the object from the ground, and although there was no physical evidence or photographs, the data provided allowed for a quick identification of the object. This case is an example of how UFO reports often have rational explanations, even if they initially seem mysterious. The witness's testimony and meteorological data were key to solving the mystery of this incident.
