Having worked nights for 4 years, we often watched the i.S.S pass over. this is bright white, every one and a half hrs. this flew exactly like it only more orange in colour, i was in compltete quiet walking mt dog by hastings caslte, no noise,no wind and no lights. came out of nwn heading ses, no noise at all omitted, so probably really high alt, no way was it an aircarft, maybe just over a minute in view. went home and looked up i.S.S , didnt pass over u.K last night.
