The Friday File: Since 1974, there have been almost 90,000 reported UFO sightings worldwide, most in the USA! Washington State is number one in sightings per capita (and number two in total sightings behind California) followed closely by Montana and Vermont. Other states with relatively high per capita sightings: Arizona, Idaho, Maine, New Hampshire, New Mexico and Oregon. Sightings peak between 7PM and 11PM, especially on Fridays. Surprisingly, no Colorado!
