Good pilots and ground crew would all ways keeps the planes clean, not just because they took pride in there machines but having a clean aircraft could give you an extra 10 knots or so and having just that slight advantage could mean the differents between life and death.

Any way don't know if you guys no, but SOW has a built in weathering layer for all aircraft. So as you fly along in your plane it will slowly get dirtier and dirtier as well as other wreathing effects like paint chips will appear.

If you look at this screen short you can see a wreathing slider so you can set how weathered your plane and others is at start of the mission.
