(National UFO Reporting Center,
Quote from the report:
“A UFO flap covering the area of North
Dakota , South Dakota , and Minnesota began on
November 8th. The sightings, made during nearly every hour of the day and
night, continued until December 2nd. More than 85 separate visual sighting
reports from some 60 different localities were received from the three state
area. Due to the unusually large number of reports, it was possible, in some
instances, to determine that the same phenomenon was seen at widely separated
areas. In other cases, the sighting reports indicate a great number of
different objects were aloft at one time over different areas.”
