UFO Sightings Map:
Three arbitrary eras are shown here in colors. Blue spots show
UFO sightings dating from 1535 ad thru 1959. The middle years
1960 - 1979 show in violet, and the most recent (1980 to present)
appear in green. That last era shows most densely in Denmark.
Scandinavia and Region

SUFOI group in Denmark,
UFO Norway and of course

Even before the collapse of the Soviet Union, reports filtered out of
Estonia, Latvia, Lithuania and Russia etc., but those seem impossible
to verify. Even now, an occasional message will make
the rounds offering to sell UFO crash debris from the former USSR.
