UFO Sightings Map:
Equatorial South America
It is nearly impossible to get solid UFO sightings data for vast regions of the
Amazon rain forest and high Andes Mountains. Sightings counts mirror
population density, strongly favoring places with good communications.
Venezuela has the most Blue spots, indicating reports prior to 1960. One goes back to 1886. A vibrating hum and penetrating beam sickened a family per Scientific American magazine.
Sightings from the "middle era" (1960-1979 in violet) are most numerous and widespread.
North-eastern Brazil had a rash of events in the most recent era (1980 to present, in green). Jacques Vallee and Bob Pratt brought most of those into the English language UFO literature.
