I was in my living room, looked out the front picture window and seen a star, then the star moved slowly straight down. I was only 12feet from the window and the star moved one foot down the window and then sped up and made a quick left turn for 8 to 10inches on the window, which then caused the star, now not a star, to be hidden by a neighborhood tree. I jumped up went on the porch. Then it stopped, shot back in a split second, started back up, stopped, then shot down below the tree and house line and disappeared.Nothing I know moves like this, as fast or these maneuvers. The Selfrige air base is near me and I have observed all sorts of aircraft and more during the air show. This was nothing like that and no where near that direction.
