UFO Landings & Traces:
This map shows UFO Landings and Trace Cases in Europe for all dates.
Italy, France and England have the highest densities, followed
by Spain and Portugal. Germany and Eastern Europe show few
sightings, mostly because I can't read those languages.
Europe .. all dates.
As with South America, L+T type events take place in the countryside.
With non-L+T sightings removed, we see that this interesting set of
records scatters thinly into Eastern and far Northern Europe.
The single year of 1954 towers above others for this data set,
as does the month of October from that same year.
A resurgence is seen in between about 1974-1978. After that,
UFO sightings reports fall back to background levels.
