It'd be great to have everything on board, however...
Was talking to a man in the know a couple of months ago who reminded me that the (Mil) requirement is for a helicopter with a winch - period. Anything else is a (sensible) bonus, so all our EIEC trained crewies etc really hang by a budgetary thread. My answer to him was that there's not much point sending the expensive chopper if you merely bring back a body instead of a casualty. His reponse was they should count themselves lucky they get anything.
Merits in both arguments!
