🇺🇸 USAF — Project Blue Book
In December 1967, a witness in North Culter, Maine, observed a reddish-orange object emitting a humming sound. The sighting lasted about 10 seconds and was noticed as the object's lights drifted downward. Although the report was submitted, no official investigation was conducted according to the Air Force's procedures at the time. The case was returned to the local air force base for further review, but no additional findings or physical evidence were reported.
