🇺🇸 USAF — Project Blue Book
In September 1960, a witness in Grand Portage, Minnesota, observed a large object with bright red lights moving slowly over Lake Superior. The object, resembling a tank on a water tower, ascended to about 700-800 feet, moved west, returned east, and finally disappeared behind a hill. The sighting lasted 15-20 minutes, and the witness remained calm. Although a helicopter was considered, no evidence of one was found. Authorities concluded it did not pose a national security threat.
