"Largest holes? What hole is there that a B-24 fills? "
You're absolutely right Raub--there ISN'T any huge hole that the B-24 fills.
I even said that in an earlier post.
I feel ther biggest holes in AH are the lack of single and twin-engine attack aircraft, and early to mid-war Pacific planes. Early-war Euro planes, particularily Eastern-Front, are alsao lacking, but not as badly.
Once these holes are taken care of, THEN it's time to come back to planes like the B-24, He-177, ETC.
