Crab,
There is no black art in SAR, period. Any average to above average RN crew are perfectly capable of conducting SAR.
And as for your disparaging of the recent Lynx rescue...it is beneath contempt. The reason they succeeded is because it is an RN aviator's DNA to be able to rescue people in most circumstances - without the need to think they are "special". They operate in the harshest of conditions every time they deploy to sea. It is why the RN FAA will continue into the record books long after RAF SARF has been forgotten. i.e. Jan 1st 2016!
