No, they are not using it for freight. They've used it for surveillance and for looking at the hydro lines and so on, but they have not invested heavily in using this. Although they have a problem in Siberia that's very similar to our problem in the north, and they are probably the closest.... But they've shown that airships will fly year-round. It's just that they haven't done that much work with the cargo.
