🇺🇸 USAF — Project Blue Book
In August 1958, a witness in Beatrice, Nebraska, spotted a glowing object that changed colors. The object, the size of a coin, moved like a pendulum for one and a half hours. Despite the duration of the sighting, no photos were taken and the data was deemed insufficient. The report mentions that the object cycled from white to red to green, sparking curiosity and debate among researchers at the time.
The official report did not reach a clear conclusion, but highlighted the unusual nature of the movement and colors of the object. It was recorded as a ground visual observation, without radar confirmation or photographs. Although several options were considered, from balloons to astronomical phenomena, no definitive explanation was reached. This case remains a mystery in the history of UFO sightings.
