How do you think that airports in Canada, Scandinavia and Russia manage ? Do you believe they close down for 6 months of the year ?
I think we have to apply a little bit of understanding here.
Mrs Strake hails from Northern Siberia where the temp is around -40c Jan to March. We happily fly in there from time to time landing on a runway that is part iced up, part cleared. It's a bit bumpy but otherwise, fine. The fact is, they don't clear the snow/ice simply because at those temps most of the water is removed from the atmosphere and surface and the ice is like concrete. The problem comes at the beginning and end of season when the temps are -10c to 0c. That's when people start falling over and cars have prangs.
In the UK, we just don't have that sort of weather normally so it would be ridiculous to plan and pay for it. Anyway, after a week or so, either everything clears up or we all start getting used to the conditions.
