🇺🇸 USAF — Project Blue Book
In November 1956, a witness in Lexington, Kentucky, observed an object glowing with reddish and blue colors, described as a luminous half-circle. The object was seen from the ground and no photos were taken, making the available information limited. The observer mentioned the object split into two, adding mystery to the sighting.
The official evaluation concluded there was insufficient information to determine the nature of the object. An additional form was sent to the witness to obtain more details, but the case remained unresolved. This incident was categorized as "Insufficient Data," and no official report was generated. Despite the lack of clear answers, the case remains an example of many sightings without explanation.
