I stepped outside the front garage door and saw two stars, one to the southwest and one to the south. the one to the southwest was higher than the one to the south. because of this i watched the one to the south and then after a minute it climbed 10,000 to 15,000 feet and changed shape into a jet airliner that looked black and had the flashing lights like an airplane would have but, made no sound like jet engines would make. then the object flew off to the west out of sight.
