May 24, 2015: Sighting in private valley in foothills of the Great Smoky Mountains near Maryville, TN during pig roast at around 1:30AM. At the firepit with 4 other friends listening to acoustic music, I was surprised when a bright light lit up the area, at first wondering why a car was coming up the hill driveway with bright lights on. But I immediately realized it wasn't a car because of no noise and the light was too bright. I turned around to my friends who were exclaiming, "What was that?" And I said, "Yes, what in the world was that?" Apparently, a flat object flew over the small valley, and created a bright blue-white light flash illumination with no sound. One of my friends clearly saw the flat object and it's path over the valley, one saw the object out of the corner of his eye disappear with flash beyond the tree line. We all saw the brilliant blue-white light flash lighting up the valley. There was no crash or explosion! We are all still in agreement that it was not natural..i.e. meteorite. No reports of meteorite crashing or burning up in area. Several days after our incident, a new crop circle was discovered in Gray, TN which is 123 mis. straight from Maryville. This is the second crop circle to be formed in the same field location: first one discovered May 13, 2013. I attached the crop circle photos to this report.
