The real unanswered question is why the 3 injured crewmembers were not taken off the sub on Tuesday evening - both Valley and Prestwick had SAR helicopters sat waiting at Ballykelly for the word to go. Instead the poor sod that died was left for nearly 24 hours until Wednesday afternoon and then collapsed in the conning tower just before winching - he could have been in hospital by midnight on Tuesday. The captain of the sub would appear to have some questions to answer. Yes the weather was not great at the time, it was 20G30 and 15 - 20 ' seas but lots of people have been winched off much trickier things than a sub in much worse conditions.
