To follow up my own post (sorry), I will give an example. During my career, I have had the misfortune to have dealt with at least five major incidents. These included three bombs, when the IRA were operating in London, and two train crashes. On the fourth occasion, despite the fact that I was nominally in charge of the Blood Bank, the person in charge of Haematology (who was my line manager, and who knew basic blood transfusion, but who had never dealt with a major incident in his life) happened to be around, and "took charge". I cannot give too many details, otherwise personal identities would be revealed, but suffice it to say, the result was near chaos, and the victims survived "despite", rather than "because of". This sounds very egocentric on my behalf (for which I apologise), but it was, nevertheless, true. :mad::mad::mad::mad:
