Hold on that is not entirely correct. Here is what happened, during the battle of Britain German strategy was to bomb RAF targets, however within weeks (the Luftwaffe estimated 2 weeks the RAF 1) of total collapse by the RAF a German bomber flight missed it's target and dropped it's bombs on London instead. The Brits responded by bombing Berlin, Hitler then failed his sanity check and ordered the switch from bombing RAF targets to bombing civilian targets. The Brits proceeded bomb the hell out of the German cities and factories.
A) any Luftwaffe estimate of RAF collapse was way off. Reichsmarshall Goring was exaggerating massively to keep on Hitler's good side.
B) The UK had material and technical advantage in aeroplanes over the Germans, along with sufficient pilots to fly them.
C) Radar.
The Battle of Britain never really put the UK in danger. Once Hitler (or his generals to be more exact) realised that Unternehmen Seelöwe was a non-starter there was pretty much nothing the Germans could come up with to compromise the UK in the war.
Edit: I've just seen what you've responded to Dachs and LightSpecta with, and I'd give you the following warning. Whatever you're reading drop it like the plague, for it is delitereous to your brain and feeding you obvious falsehoods.
