Why are some aircraft able to fly in extremely cold climates (such as the Poles)? What causes them to not freeze over?

I am a huge fan of flight simulation games (and aircraft mechanics in general), and this is a question that has always been interesting to me. Why are some crafts able to fly in super cold areas without freezing over and inevitably plummeting, while others have basically no chance of staying airborne?

They are designed for it. At 40,000 feet the outside air temp can be -40to -50f in temperate climates. It doesn’t freeze because there’s not much moisture up there. Flying in the Arctic is not much different. Flying through clouds is a different issue.
