Interesting video. And shows how someone with practical skills can solve problems that would be theoretical otherwise.
I like the remark 'it's a pretty joint. Would look nice in an Islington cafe'.
But how about the Vikings sailing to Shetland?
They find out how to use a tarbert to cross the boat overland from the North Sea to the Atlantic.
And the final shot of the ship with sail up gliding past a big oblong hole through the cliff seems to suggest that perhaps they weren't so accidental and natural after all.
