🇺🇸 USAF — Project Blue Book
In April 1967, a witness in Tucson, Arizona, reported seeing an unidentified object. According to the testimony, the object appeared in the sky and remained visible for a significant amount of time. The description included details about its appearance, though no specific sounds or lights were mentioned. The official U.S. Air Force report concluded that the object's nature could not be determined with certainty due to insufficient information. It was suggested that the object might have been a hot air balloon, but this was not confirmed. The case was filed as inconclusive due to lack of sufficient data.
