Mr. Woodruff saw the object or flying disc first and said he saw the thing travelling through the sky. We did not believe him at first but when he was so concerned about it we stopped the car and got out. I had my camera so took a picture of it. There was a bluish streak left in the sky which could not have been a cloud formation. It was a definite trail and caused the clouds to break open as it went through. It cut a clear path through the cloud and you could see the trail right through the cloud, it looked to be travelling in a big circle and it left sharp edges to the clouds. The trail looked as if an object passed through similar to that of a pebble leaving a ring in the pond. There was no difference in color. It looked as if the object broke and cloud and left this opening.
