UFO Sightings Map: North America 1940s

The top map at left shows UFO Sightings for the entire decade of the 1940s, including the famous wave of June-July 1947..

[1949] in the upper-right corner refers to the last record retrieved as this map was generated.

A zone of seeming inactivity runs North and South around the 100th Meridian (100 degrees West Longitude) from the Texas Panhandle through the Dakotas. This pattern persisted (with notable exceptions) through the years.

Since about two thirds (2/3) of the sightings for the entire decade took place in 1947 alone, that map will look nearly identical to this one.

Now scroll down and compare maps.

<= This is the same map, but only two months of sightings are excluded, June and July of 1947
Two months out of 120. *U* listings worldwide drop from 1047 to 489, less than half. North American sightings fall from 777 to 256, less than a third.

For the two excluded months, sightings were more than 60 times "abnormal". See this daily Histogram for 1947 only.

Here again is 1947 only, the entire year.
Since the overwhelming majority were in June-July of 1947, you can add the sightings on that map, to the ones on the bottom map at left, and arrive at the map display at the top of this page.

At least one pattern did not disappear with the first great wave removed, the North-South alignment of sightings from New Mexico through north-central Colorado. Also note the short string of sightings in south-west Idaho.
