Brilliant fireball shooting across the sky that crashed behind a mountain illuminating the entire valley.I was driving on a dirt road driveway next to a large, open field. I was about half way around it when a HUGE brilliant white/blue light with a long trail (Comet like)came shooting across the sky. The light was so bright that the inside of my car was completely illuminated and I actually squinted my eyes while looking at it. The object was at least the size of 10 houses with a tail of about 100-200 yards long. The ball passed behind a mountain range that was in the valley where I was located. It appeared to have crashed because it sent a triple flash of the equivalent bright light across the entire valley and skyline of the mountain range as far as I could see. The mountain that it passed behind is uninhabbited with no known roads. I have not heard of any other witnesses but there are other houses next to and in the field that I was passing. I know what I saw was definitely from another lifeforce.((NUFORC Note: Date is approximate. PD))((ADDENDUM FROM WITNESS))The direction that the "UFO" came from was NE to SW. It was on my left side and went from behind me to infront of me. I was on the edge of the field on the road, it was over the field.For the date, I really wish I would have written it down. It was the summer of 96 between June and August of my Junior to Senior year of highschool. I seem to remember it being in mid-July.Metalline Falls is a very unpopulated area and no we don't have a local paper for about 50 miles. There were no other known sightings of it from anyone that my family or I have found.The picture is still very vivid in my mind eventhough it happened in 1996. ((name deleted))((END))
