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?

The South Pole (average summer temperature -40) has two main aircraft types present, DC-3s and LC-130s. They’re both really old. The jet fuel they use is called AN8, which is modified to flow at very low temperatures. The LC-130 pilots leave the engines running when they land at the Pole, since it’s a lot easier than trying to start the plane cold. The DC-3s have special heaters to make them able to start somewhat easily in that weather.
