VERY interesting piece in the current ECONOMIST (you need a subscription to

read it) about the possibility that terrorists groups like Al Qaeda are

moving from the air to the sea. Pirates in the seas of Southeast Asia are

suddenly doing strange things: taking over ships, steering them for a few

hours, as if for practice, then departing with cash and some skilled

seamen–perhaps to use them as instructors. Blocking key choke points like

the Suez or Panama canals could cost billions. Not to mention the chance of

a terrorist-organized Halifax-style

disaster, that might easily kill more people than did 9/11. One more thing

to worry about.
