I keep thinking of an alternate LAX of the 1950's with civil Constitutions and C-99s along with littler aircraft like Stratocruisers. If the ICC had not intervened, perhaps full-cargo variants in the markings of Santa Fe Air Cargo and others (before being legally terminated, Santa Fe Air Cargo did fly some DC -4's with full "warbonnet" livery as applied to their diesel-electric locomotives).
