I was driving a car going south on the road that I indicated moving at approximately 50mph when I looked over and saw the fireball. I am not sure if this effects the distance that the fireball appeared to travel. I only saw it for such a short time that it is difficult to come up with all of the exact details. I hope that my information is helpful. I tried to be as accurate as possible. I hope that it helps. At least I know that i wasn't seeing things!!
