Bright light that persisted for quite a while, about 100 feet above the ground shot up and disappeared when I got out to look closer.

In early October, 1966, I was driving late one evening going with a friend from Troy, Ohi to Conveington, Ohio on Stare Rt. 41--about thirty miles northwest of Wright-Patterson Air Force Base in Dayton, Ohio.  While driving, I became aware of a light in the passenger side, front-seat window which persisted for some time.  At first I thought it was merely reflection from a farmhouse or barnyard light.  But after passing some houses, it continued.  Curious, I stopped the car alongside the road and got out so I could look over the top.  I saw the light about two hundred yards from the car in a field, maybe a hundred feet off the ground.  Immediately it shot straight up and faded out of sight, almost instantaneously.  Amazed, I excitedly got back into the car.  But my friend had seen nothing, and didn't want to discuss the incident.
