A bright light that went from moving slowly to extremely fast to stationary and then gone with no sound or acceleration.I was driving home from my girlfriends and it was late. There were no other cars on the road. I saw a light that was steady and not blinking. It was just a plain white light. It looked like a bright star. It was moving low to the ground and moving slowly. At first I thought it was a helicopter and just kept watching it because it stuck out in the air over the open fields. Then it started moving very fast in one direction and then back in the same direction it just came from. When I say fast I mean very fast. It did not accellerate it was instantly moving fast. It did this for about half a minute going back and forth in the sky. Then it stopped moving for a few seconds all together and was stationary in the sky. Then it started to move slowly around again like when I first spotted the light. I then proceeded to pull over and tried to get a video of it on my phone. When I was trying to get any kind of picture resolution on my phone it just shot into space so fast and was gone. To someone reading this it might seem like a helicopter is actually what I saw looking for something or someone. But there is no way a helicopter could move the way this light was moving. I would not pull over to look at a helicopter. I instantly called my girlfriend and told her what I had just seen and she said I was crazy. I know that what I saw was a ufo there is nothing manmade that could do what I saw this thing do. I never believed in ufos until that night and now im a believer.((NUFORC Note: Source indicates that date of event is approximate. PD))
