It was approx.930 p.m. I was standing on my back deck barbecuing a steak, I looked up at the sky wanting too star gaze. I looked west then too the east, there it was, colorful pulsating lights moving in a NW direction, moving smoothly and swiftly no noise, then it was gone. I never in my life seen such a air craft, my father is a former pilot and I love aircraft and that was not any aircraft I've ever seen in my 52 years.
