We were standing in the backyard around 6:00 PM and the blue sky was cloudless. I looked up and clearly saw a silver object flying quite high at a slow pace toward Roanoke in a southwesterly direction. I thought it was a plane, but it was really too far to describe its shape. I said out loud that it’s heading to Roanoke. My wife said it is too high to be landing in Roanoke (about eighty miles from where we stood.) We were watching it and it vanished in an instant. Nothing gradual about it. We saw moving slowly and then it was gone. There were no lights or no com trail.
