🇺🇸 USAF — Project Blue Book
In 1947, a civilian observer in Boise, Idaho, reported seeing an object emitting a pulsating blue-green light. The object appeared in the southwest and disappeared in the northeast, crossing over the mountains. Despite the visual description, the lack of details such as exact time, speed, altitude, or size made it difficult to form a conclusive evaluation. Investigators suggested it might have been a fireball, but no confirmation was made. The case remains unsolved, with little data to analyze.
