UFO Sightings Map:
USA: 1947 - 1957 - 1973
The original *U* UFO mapping software allows layered maps with up to
four separate sets of data filters. Here, three major US waves are
superimposed with sightings for 1947 in Red, 1957 in White,
and 1973 in Blue. Color was enhanced for contrast.
The 1947 wave was mainly a western and mid-western affair.
The 1957 UFOs spread Southeast from California, and back up again toward Lake Erie and beyond.
The 1973 October sightings took place predominantly East of the 100th meridian.
It almost looks planned. No large part of the USA was left untouched by the sum of these three wave years alone.
