Very bright light moved from one side of sky to the other and in circles at an amazing speed, changed direction and flew off.

My wife and I came home from dinner at my parents late, around 11-12pm.As we climbed the steps to our 2nd storey deck which has a very large field of view, we saw a very bright light flying from 1 side of the sky to the other. It was going around in circles, reversing direction, stopping, accelerating, and then slowing down,then it would speed back up and circle around and back and forth, it was crazy. It was very far away, big, and flew all the way from one side of the sky to the other on the horizon as fast as you could move your arm with a sparkler on 4th of July. It freaked my wife out. All of a sudden she wanted to know about ufos. I own 2 local businesses, my wifes a legal secratary. It wasnt a helecoptor, meteor or anything easily explained, and it definately was controlled by something. It flew off and got so far away we couldnt see it anymore, it just faded out. It was a crystal clear night, you could see every star in the sky. We arent nuts. There was a commercial aircraft flying with wing lights flying that was closer and lower then it, and it was going way slower then the ufo. It was silent. Im not big on giving my address on the internet, but e mail me anytime. ((name deleted))
