First, I'd slap those twits the Brits. Then I would install counter rotating props on the Mossie.

Second, I'd kick the USAAF for spending all the extra $$$ on teh P39 when they could have dumped the funds into the P40x and made them better earlier. I'd have more powerful engines installed into the P40 earlier. I dont think the P40x's potental was ever reached, imo.
Third, I would kick those twits the Brits again and get fuel injection into the Spit I and Hurri I prior to the BoB.
