🇺🇸 USAF — Project Blue Book
In November 1956, a radar operator in Point Arena, California, recorded the presence of two aerial objects that drew attention due to their unusual size and trajectory. The objects, slightly larger than a DC-7 aircraft, appeared at a distance of 175 to 185 miles and at an altitude of 21,000 feet. They were moving slowly, between 6 and 10 knots, following an erratic path. One of them remained on the radar screen for 99 minutes, while the other was observed for 61 minutes. Despite the long observation time, there were no photographs or visual testimonies, complicating a definitive identification.
After analyzing the data, investigators concluded that the objects were likely weather balloons. Weather conditions and the upward trajectory of the objects supported this theory, although it could not be confirmed with certainty. Other possibilities such as aircraft or astronomical phenomena were ruled out. An RC-121 aircraft conducted a visual inspection of the area from an altitude of 4,500 feet without finding anything. Despite the investigations, the exact origin of the objects was not determined, but the available data clearly pointed to a conventional explanation.
