you're also forgetting something called critical mach, the speed at which no ammount of propulsive force will make the plane go faster. most planes reach their vne (velocity never to exceed, i.e. the speed you are in danger of breaking up) first but their are a few planes in the game i'm sure that will hit critical mach limit before vne. the f6f and f4u are good candidates for that.
