As an OAP, and a life long believer. Is there anyone else, of my age, who went to school in the Croydon area, round about 1952-53? I know that's asking a lot. But I think every kid in every school in the area, on one particular day, must have seen the very bright disc in the sky, almost directly overhead. It was clearly, solidly defined and totally stationary, so, no chance of being tagged as a weather balloon. Unfortunately, being of such a young age. Other things soon distract young minds, so it was soon forgotten. Although that afternoon, at a friends house. Waiting for him to come home from his school. The first thing he blirted out, on arriving home was, "We saw a flying saucer at school, today".
Although I am now 65. At the time, I was 7 or 8 years old. But can clearly remember a shiny solid disc, it's edge being brighter than the centre.
