It was not Churchill's Strategy, He took charge on the day France was invaded and wanted to send planes, but it was too late. There was no time to send in the mechanics, radar, train foreign pilots, etc,

Like I said, if Dowding knew that France was lost he should not have sent any planes. But France, Belgium and Holland were far from lost. The combination of the allied air force, army and navy was formidable. The problem is that the most valuable assets were kept in reserve, dooming the rest.
It's as if instead of sending Wellington to Waterloo, he had been kept in reserve, because his troops were too valuable and Napoleon could invade Britain if he were not available. Or as if Nelson were kept away from Trafalgar or Abukir, lest Britain be invaded. Britain always won because it used aggressively its best assets. Had Dowding sent in time the best planes and allowed the best Polish, French, Belgian and British pilots to use them, Hitler's Bf-110s, Bf-109s, Stukas, tin tanks, etc, would have been wiped out.

It is precisely my point that Dowding was left with excellent Spitfires and lousy pilots (the worst possible situation), because the good pilots were sacrificed flying mediocre planes or lost when France, Holland and Belgium capitulated.

The BoB was not won because of Dowding's strategy, but because of Göring's and Hitler's stupidity. Göring sent only small waves initially with disastrous consequences, allowing the few British pilots to defeat each small wave at a time thanks to Radar. Had he sent in 600 planes at a time from the beginning, he would have wiped out the Radar stations, planes, pilots quarters, aerodromes, etc, in a large enough area to invade. The RN could not have done much against German planes in the strait of Dover. Hitler then ordered bombing London, etc, in reprisal for the bombing of Berlin and wasted any oportunity of winning the BoB.
