UFO Sightings Map: EuropeThis map shows UFO sightings for all dates in Europe, recently refreshed and brightened to 4 pixels each.
Place-name "tags" show in dark green characters, e.g. GER for Germany.
Sightings densities for each country depend heavily upon the activities of their respective UFO groups, journals and investigators.
Note the disproportionate sightings densities for Britain and France, compared to Germany, Holland and points east.
Cultural factors aside, the simple fact is that Larry Hatch can't read German, Dutch, Polish etc., introducing a definite cultural bias.
