Wouldn't the third runway be covered in the same amount of snow, Rainboe? So wouldn't they still have to close it to allow it to be cleaned? It's going to be the same problem, I'm afraid, so the place would still have to close until at least one runway is cleared and then we have to think of getting aircraft from whatever runway is open to the terminals, and that brings in other issues with a third runway due to the extra taxiways if they are linking the third one to the main airport complex (honestly can't remember it it is going to be "stand alone" or connected to the rest of the place)
