UFO Map: North America 19471947 UFO Sightings show as white dots here While all 1947 events are displayed, the vast majority took place in July alone.
The size and suddenness of this wave was unprecedented. Terms like "great airship" and "ghost rockets" fell by the wayside. The Flying Saucer age began with a bang.
Note the string of sightings extending southeast from Washington State. Other groups and alignments contrast with large vacant areas.
New Mexico and southern Idaho are full of UFO reports, but very few came from upstate New York, or western Pennsylvania. Note the band of relative inactivity around the 100th Meridian.
