🇺🇸 USAF — Project Blue Book
In July 1964, two workers in Brigham City, Utah, observed two "V"-shaped objects moving rapidly from north to south. The objects were in single file and disappeared into the darkness within seconds. Although initially considered a UFO sighting, the evaluation concluded they were likely low-flying birds. The witnesses' description, along with the clear weather and time of day, supported this interpretation. The observers, both emotionally stable employees, reported no physical effects or other unexplained phenomena.
The detailed report included precise meteorological data and observations, but no photos or radar were used. The official conclusion was that there was insufficient evidence to classify the event as unexplained. Despite this, the case remains an example of how UFO reports are often explained by natural or known phenomena.
