🇺🇸 USAF — Project Blue Book
A bright object was sighted in Maine on February 5, 1961, at 07:44 UTC. Witnesses in Vermont, Maine, and Massachusetts reported a round object the size of a full moon with an intense blue glow. It left a bright trail as it moved northeast and disappeared over the horizon. Observers included civilians and military personnel, and multiple reports aligned on the details. Although a meteor or decaying satellite was considered, no conclusive evidence was found. The Air Force concluded it posed no threat to national security.
