Yeah, lets not confuse real life with AH2. Bombers were death traps. We've discussed this before. Guns on bombers were almost entirely ineffective at destroying enemy fighters (Saburo Sakai had no problem downing a B-26 in his Zero). The Mosquito was almost certainly more survivable and adaptable than the B-26 in real life. Lets not forget how inaccurate level bombing was. U.S bombers were lucky to get a bomb withing a half mile of the target. This is not due to crew ineptness, the technology simply wasn't there.
So we have the Mosquito- Heavily armed, very fast, long range, and surprisingly agile.
and
The B-26- Level bomber, cruising speed around 200mph, defensive gun dispersion of 20-40 feet at 500 yards, chock full of high explosives, gasoline, and fragile humans.
But in the game with our laser .50 cals, 300mph 'cruising speed' and base-busting bombload, it's definitely a war winner.
