Fascinating stuff Chaps. Undoubtedly a huge percentage of 'lights' in the sky are stars and planets, especially when viewed near the horizon 'cos of the 'slant angle' effect through the atmosphere which magnifies and distorts things as when the slant angle through haze makes viz poorer than when looking straight above you. The reports which really intrigue me are multiple sights of 'mother ships' such as cigar shaped objects. Surely these can't be optical illusions or mass hysteria? Where these objects come from is, of course, another question.
