My brother, his girlfriend and my wife were all at the drive in. we were sitting in the back of his truck just around dusk waiting for the movie to start, out of the corner of my eye i notice something move sharply then slow down out of my preferial vision. then i noticed it was a red glowing light that brighten and dimmed, and the shape of it was distorted like a cloaking device in the movies and the surroundings were being bent by light or what ever the ship was producing. after which the red light completely dimmed to the point that you would not have seen unless you knew it was there, however its cloaking device was very noticable as the ship flew just 20 feet over head slowly like it was watching or monitoring us at the drive in. after about 2 minutes the ship passed and went in north eastern direction while climbing at a rapid rate.
