🇺🇸 USAF — Project Blue Book
A witness in St. Augustine, Florida, observed a round object the size of a softball, white or silver in color, very high in the sky. It was seen through binoculars (of unknown power) for one hour and twenty minutes on July 31, 1956. The object then simply disappeared. Although the characteristics match those of a balloon, the lack of complete information classifies this sighting as a possible balloon.
