At approximately 14.00 hrs whilst playing a game of table tennis outside, i looked almost directly into the clear sky above me. As someone who is an extremely keen aviation enthusiast, i am familiar with heights, shapes dimensions, speed etc....

Anyhow what i saw was an object that was a perfect circle, it had approximately 6-8 segments and was a bright silver, i stood and watched it for at least 5-6 seconds and then i could see it no more. I believe that the object was approximately at 60000 ft and probably 200ft in width. It was static and not moving.
My companion asked what i was staring at and i explained a silver disk..
I have never dispelled the fact that it could have been a weather balloon but i couldnt understand why its appearance was suddenly gone. Ever since that late British Summer i have always been interested in UFO siteings. With regards to my eyesight i do not wear glasses and 14 years later i still have a perfect eyesight and am compelled to scour the skies in both daylight and night time, as i know things are out there.
Date may be approximate.  PD
