Hard to dismiss something if you seen it yourself. I have, but not the kind of "UFO" like you'd think. It was a ball of fire, the color of flame, maybe 3-1/2 feet to 4 feet across. Appeared and floated across the clearing in front of my brothers and myself..I was 11, they were 9 and 7. Bright sunny day, 7PM in the evening August 26th 1979.
We ran like scalded cats, told our father, and he said it was a bad omen. We pressed him to explain, because we were freaked out, and he would only say "Something bad is going to happen".
12 hours later our mother was killed. When my much older brother, the one who drove over her with a car, came the next morning at 6am to tell my dad...my dad knew something was bad wrong..I clearly remember him looking out the window as the car pulled up the long driveway..he kept saying "Oh no..Oh no..Oh God..Oh no..." He was right.
My other older brother saw something in the sky once, about 12 years ago. He was driving his son to karate class.. It was "Huge", motionless, and dark colored. It was stationary, about 150 feet in the air, over the edge of a small field next to a neighbor's house about 3/4 mile down the road from us. He tells me it was the size of several houses, and of a shape like no flying thing he has ever seen. It scared him so bad he took off in his car as fast as it would go. And I mean to tell you; he is not a man who lies, or who scares easily. He was scared for his son, who was 11 or 12. His instinct was to run. As for his son, he saw it and said the description is exactly the same.
