After exiting the house to take dogs for a walk my wife and I were drawn to a bright yellow light and tail moving across the sky from SE to West. We thought it might have been a plane on fire at first but there was no noise and it was moving faster than a plane. We were both shocked at what we saw. It had a shape like a rugby ball and a tail which we thought could have been flames from an engine. It kept its height until it appeared to descend a bit as it left our sight.
