Not all of the sightings were centred over Denmark and one event over Greenland is attracting attention.
On the 5 January, 1981 at 12:50 a flaming, square disc was seen approximately 45 degrees over the frozen land near Thule Air Base. It then vanished as suddenly as it had appeared.
Coincidentally, radar stations at the American base recorded an unidentified flying object on its radar at 12:50.
Air Force Captain Thomas Petersen, who has an extensive knowledge of the files, commented that any unresolved sightings are handed over to the Scandinavian UFO Centre, if they request it.
