I stumbled across this amazing post on http://www.ufo-blogger.com today.
Over the past 15 years, the Davenport, Wash. – based National UFO Reporting Center has collected more than 30,000 reports of UFO sightings through its hotline and Web site.
The visual results of these reports is amazing to see.
The first plots every sighting as a small yellow dot, with lighter colors representing a higher density of reports.
Visit their site to check out the other maps showing this data collected. It is truly amazing!
