Moggy,every inch of you is RAF pride,and u have any right to do it,but u need to be objective: Coventry was flattened and a good part of London was devastated.. had they kept on hammering airfields you would have had no chance to defend yourself. I'm not offending anybody's memory,I respect fighters on both fronts,but you need to get yourself a better source of info,not just watching documentaries.. You show poor understanding of aviation (your conclusions about engines is pretty senseless),I'm only trying to explain things in an objective way,and I know that sometimes I come out a bit blunt,but you can decide for a life in denial or listening to people that actually spent hours on books and met many historians.. Ask in person to Prof Holland what he REALLY thinks of the BoB..he's quite a renown English historian..
