Well I dont think membership in the CAF requires an oath to "support and defend the Constitution of the United States against all enemies, foreign and domestic..." But yes you are probably the "youngest" WWII aircraft rated aircrewman here...
and IIRC you got some of these too, so a C-130, C-141, and possibly other types such as the UH-1, CH-47, and UH-60 enter as build possibilities
