Me and my flatmate (both rational professionals and sober at the time) were walking up peckham rye on the east side of the common at about 11 pm on saturday 4 august and saw 3 or so lines of quite small orange fiery lights, each line with about 4 lights in it, moving almost vertically up from the horizon near crystal palace masts, then, when they were fairly high in the sky, their trajectory flattened out sharply and they began to travel east over east dulwich and peckham rye. the speed and altitude were similar to that of a jet plane, but the flight path, formation, numbers and appearance were quite different. we watched for a few minutes. we left the road and went into our apartment building to get binoculars and look from our roof terrace; in the couple of minutes it took to get there, they had disappeared. did anybody else see this?
