flying for your life

British intelligence has foiled an attempt to blow up planes bound to the US from London, it seems. The terrorists were apparently intending to bring their explosives on in hand luggage. (I have seen no information about how advanced these plans were.) The fallout for passengers is disturbing. They are being refused permission to bring liquids onto flights in hand luggage, including, I assume, water. There are serious health implications, as plentiful water is essential when one's flying long distance, as doctors repeatedly tell us. It's now up to the airlines to supply the large quantities passengers require to avoid dehydration, and not to charge for it. If they don't, the health risks of flying will multiply exponentially.
