Perhaps it should be understood that SAR can be done very differently depending on requirements, equipment, environment and particularly culture before tarring all SAR operators with the same brush.
UK SAR has an excellent safety record but how things are done in UK compared to EIRE will not be identical - different ethos, different companies providing the crews, different operational tempo and different equipment levels.
I know that this accident will have been the subject of crewroom discussion and training team focus in the UK and probably across the world and if that adjusts small areas of operation to remove even one hole in the cheese then it will be a good thing.
However, the idea that this will lead to a root and branch review of how SAR is done is fantasy unless you just don't want people to get rescued.
Dedicated SAR crews have worked for years to identify and minimise risk wherever possible but the fact remains that the places you are asked to go when the job phone rings are often hazardous and the time pressures, when people are relying on you to save their lives, don't go away.
