1 Bomber Commanders. I'll find the reference to the meeting for you.
2 If the Luftwaffe were looking for total air superiority over an invasion area, they would not have been looking to fly as far as London, but rather only as far as the English Channel coast. That would have increased the 109s' combat time considerably. It would not have proved to be any constraint on the 110.
3 I think Stephen Bungay calls it the 'cock-up theory'. The less you do (i.e. you keep things simple), the less cock-ups, the more likely you are to win.
And ineptitude, yes I agree. Previously, right up to the end of the Western Campaign in the Spring of 1940, there were clear goals. For the Battle of Britain, there appears to be hesitancy, and a case of not quite knowing what to do next. For just over a month there were attacks on shipping in the Channel and up the south-easy coast of England. Then the attacks on the airfields and the land targets. Then on 7th September the major attacks on London. Doesn't seem t have been a single coherent strategy. Perhaps down to the fact that a negotiated peace was hoped for - an acquiescent British Empire leaving Germany free to do as it wished. When that didn't happen, what next? Well, knock out Fighter Command as a prelude to invasion. Which, in its wake, brough out disagreements across the three German forces. It is as well for us that that happened. Coupled with poor intelligence on the German side, and attrition that could not eventually be sustained, as well as a host of other factors.
