🇺🇸 USAF — Project Blue Book
In September 1953, military personnel at Pepperrell Air Force Base in Newfoundland observed a green object initially thought to be a flare dropped by an unidentified aircraft. However, further evaluation suggested it was likely a meteor. The object was simultaneously seen in Argentia by air traffic control personnel. Although no photos or physical evidence were collected, several nearby aircraft reported similar sightings, causing some confusion. The official conclusion was that it was a natural phenomenon, not an unidentified object.
