🇺🇸 USAF — Project Blue Book
A witness in Gurnie, Illinois, reported a round object the size of a basketball, orange in color, observed for 6 to 8 minutes. The sighting occurred on the night of April 9, 1956, but no information about the trajectory or movement of the object was recorded. Despite the witness being a 30-year veteran garage attendant, the lack of precise data prevented a conclusive evaluation.
The available information was limited, with no photographs or radar data. The responsible authority concluded that there was insufficient information to determine if the object was a balloon, aircraft, astronomical phenomenon, or something else. This case was filed as inconclusive, reflecting the common difficulty in many UFO reports of the time.
