One of the first books on the subject of AH that I ever read was Invasion, by Kenneth Macksey. The book basically describes that most reviled of all AH scenarios - a successful Operation Sealion. The basic idea was that the invasion was actually launched early - in late July, right after the fall of France, before the British have a chance to properly organize either their land or air defences. Since the almost universal consensus seems to be that the scenario is either impossible or at least ridiculously implausible, I was wondering if anyone here had ever read the book. If anyone has read it, where do you think Macksey's scenario falls down?
