Me and my beloved, in 1991, watched an object at great height on a crisp, winters evening. It was basically a white, intense dot. Me being RAF in those days, I dismissed her enquiry with “it’ll be a jet from one of the nearby bases, you’ll hear the jet noise in a moment.” Anyway, there was none, the object stopped dead in flight from speed, it then went backwards at the same crazy speed, and then forward and stopped again – no noise. So now we were both interested.
After about a minute, it accelerated so fast it was simply a streak – straight up and into space, disappearing in a second or two. I am not prone to fanciful thoughts, but this, I have no explanation and am convinced it was not of this earth.
