The above map highlights two important aspects related to UFO sightings and Airports in the US.
Regions with darker shades of blue have more number of sightings near airports, whereas as the shades lighten, the number of sightings around airports decreases. This measure is represented as a percentage to give us a relative understanding of the density of UFO sightings. Secondly, the yellow and orange points plot the top 1000 sightings closes to aiports.
One would usually expect the results to be dense near the west coast (SF/CA) and east coast (NY) but we see some surprising results! The top 1000 sightings closes to airports are in Montana and Wyoming.
