🇺🇸 USAF — Project Blue Book
A 1955 report describes an unidentified object seen near Maine. Witnesses observed a phenomenon that changed from red to green and then to yellow, without emitting sound. The sighting lasted about two hours and was reported by a civilian. Although several explanations were considered, such as balloons or aircraft, no definitive conclusion was reached. The case was classified and sent to multiple air bases for analysis.
The report includes details such as local time, precise location, and favorable weather conditions. Although an interceptor was sent, the object could not be identified. This case remains one of the many unresolved mysteries in UFO history.
