Ask the people of Hull when the towrags stole the Substation earthing
copper.
(Of course Karl Turner got in on the act and convinced the REC to
stump up for replacement electrical equipment for the consumers who
couldn't be bothered to insure their possessions)

That was a very localised outage not something like a transformer on the
supergrid going shorted turns and taking out most of south England with
it.

That example above is rather like saying that the great Heck rail crash
was something wrong with the railways;!....
