A turqoise light lit up the entire sky with no apparent point of origin.My girlfriend and I were traveling home for Christmas on Highway 14 in Walla Walla County, Washington. The area around was vast open fields. There were only three vehicles on the road that night, a semi in front of us and one behind us. We were just driving along when suddenly a bright turquoise light lit up the sky. The light didn’t seem to have a location where it was coming from. It lasted about 3 seconds then stopped. My girlfriend and I were completely tripped out. Then it happened again. This time the time length was shorter but it lit up the entire sky. I looked above us and it seemed apparent that it was coming from right above us. When I say it lit up the entire sky, I mean it lit up the sky for miles upon miles. There was no airports near us and no towns for another 60 miles.((NUFORC Note: Witness is going to try to establish the exact location of the event, and send the information as an addendum. He first reported that the sighting had occurred near Walla Walla, but the location cited above is more accurate, he now believes. PD))
