Missed opportunity of the North Sea billions

You would have to look hard to find the thin black line that keeps Scotland moving - a pipeline buried between Cruden Bay and Grangemouth. We start to notice it only when it is switched off, and learn it has been steam-driven all these years. For a two-day strike, not only are the unions getting lots of bang for their strike-pay buck, but the consequences have forced us to ask some big questions about an industry located somewhere over the North Sea horizon.
