That requires a certain amount of trust in the skill of the modder that he is actually capable of faithfully digitizing the plane. Haven't found that modder as of yet.
Besides i feel that the base game should at least give one plane of all types. That way the game engine at least properly supports, in this example, flight at that speed. Currently there is no base game plane that breaks the sound barrier (to my knowledge) so that leads me to believe that it does not realistically support it properly
