Mr Google took me straight to the audit report on the Vigilant, but there seems not to be a Viking one. The report is 88 pages long, terribly verbose, and at the end of it I could see no recommendations that suggested grounding. Shurely shome mishtake as 007 would have it. If this report is not the basis of the grounding then what is? This whole business is beginning to smell. Looks awful like civil servants covering their arses in paper.
