I wished I could get more perks from a successful C47 supply run. It's risky and time consuming. It helps keep the game interesting. It should count for more than it does.
Like all perks, it depends on other things besides you just flying a C-47. Was your side outnumbered at the time or overwhelming everybody else? The perk modifier. I think it may also depend on how damaged the base you are resupplying is. No free points or supplies to an undamaged base.
Otherwise, it really is just free bomber perks unless you're flying into danger which is almost suicidal no mater the reason.
