P.Sepsas: I watched these two stories on the BBC World too.
In reality NO airport in the world can totally avoid a shut-down during the worse snow storms BUT there is a big big difference between having the WILLINGNESS to prepare for the eventuality, which our beloved (or hated) Heathrow is not having this kind of right mind-set now. I also noticed the opinions of some readers on this forum think it might not be worth the large investments for an odd occasion. Global warming is with us and we can reasonably expect more, not less of these situations in the future.
Now that the British government (high time!) is seriously discussing the possibility of giving the relevant department the extra power of dealing with the commercial bodies running the airports in the UK in order to reduce the chances of another travel fiasco!
