IIRC, up to about 1940, big aircraft were generally flying boats due lack of huge runways...
Then the exigencies of war meant that runways were put everywhere, and enlarged to accommodate bigger & bigger aircraft. Yes, there were the sub-hunting Sunderlands ( 'Der Porcupine' to the exasperated Luftwaffe ;-), and the few Martin Mars which supplied some Pacific outposts...
So, of course, end of WW2 left lots of large, land-based aircraft and the runways for them. Only niche markets were left for flying boats & sea-planes...
One irony is that the 'floating debris' problem was later solved with a air-bubble system deployed from submerged pipes...
Without losing too much from OTL, can you find a POD that keeps lots of big flying boats ??
