🇺🇸 USAF — Project Blue Book
In July 1957, a couple in Wild Rice, North Dakota, observed a star-like object for approximately two hours. The object, ranging in color from blue to fiery brown, appeared to have a tail the size of its body and remained almost stationary in the sky. The witnesses used binoculars, which may explain some visual distortions. Despite the duration and apparent stillness, no positional data was obtained to identify the object with certainty.
Investigators concluded that there was insufficient information to determine whether it was a balloon, an aircraft, or an astronomical phenomenon. Although several possibilities were considered, the lack of precise data meant the case could not be resolved definitively. This type of observation, without positional or tracking information, was common at the time and often ended in categories such as "insufficient for evaluation."
