On our way home from bethel one night, brother in law was driving the snow machine my mother rode behind him, I was being pulled in a sled behind them both. As I was facing foreward I seen a light from behind me start getting brighter. I remember thinking it was another snow machine getting ready to pass us as this happens on the shortcut we take on a regular basis. As I looked back to check out the source of the light I was surprised to see the light not on the ground level but about 20 feet up and about thirty feet back pacing our speed. There were no noise from roters or any downwash As you'd have from a helicopter. The light was bright so bright but it didn't cast its light beyond me in the sled it sat focused on me for what seemed like eternity, I can see the outline of the ship, triangular boomerang like as it hovered silently pacing us. Then the ship stopped and shot out and away faster than any aircraft Ive ever seen. I'm not sure if they knew I was in the back of the sled when they came to check on us pretty sure I was just as surprised as they were.
