We observed a very bright white light heading west to east at a very high rate of speed. We were on the farm and had very good view of other planes off in the distance.All we could see was a big,round,white light,no other colors of any kind,it traveled clear across the sky in a very short time. No trails of any kind behind it as it sped across the sky. Flew much lower than normal aircraft do. We could hear it as it passed over us and it didnt appear to be a shooting star of any kind
