Reynolds and GeeRam,
Great posts, many thanks!
As for
the NA Mustang won the war
...this is more accurate than the hyperbole about the Mosquito (excellent though the latter was). The P-51 did reverse the fortunes of the 8th AF's campaign - as soon as it commenced operations as an escort fighter, the unsustainable loss rates of, for example, the Schweinfurt raids began to fall markedly, and the ability of the Americans to bomb targets across Europe at will was no longer in doubt (admittedly there were still heavy losses on occasion - usually when the bombers found themselves without their escort).
