Habakkuk of Ice

I have just spotted this on the BBC Radio7 website.  I've not listened to it as yet (althought I recall hearing it a couple of years ago), but the programme tells the story of inventor Geoffrey Pyke's plan to build a large aircraft carrier from ice!  Hallmark did a model of this in 1/6000 (it's still quite a large model, even in this scale) which I really must paint sometime...
