Motionless silver triangle high in the atmosphere.Saw something strange the other day while standing in my driveway. A friend of my son's had stopped by to see him, however he wasn't home and his friend and I began talking about U.F.O.'s/aliens. She brought up the subject out of the blue which is even stranger since I had never met her before until that moment. I looked up in the sky while we were talking and saw a silver triangle high up in the atmosphere. I suppose you could say it was the size of a penny considering the distance. I pointed up toward the sky and said: "What's that?' She looked up and said she didn't know__then this object 'faded' out. Further away from where this object appeared, a jet was passing. I wonder if anyone on this jet saw what we did? Guess this is another mystery we'll never find the answer to. The sky was cloudy that day so I don't know if it just 'disappeared'' or if the cloud cover was the reason it faded. Nevertheless it wasn't another jet because it was motionless.
