Training, crew resource management, and guidance/ mentoring is something I truly believe in, but it still does not ensure common sense or good judgement with some people.
Very true Helilog but there is often a sense of duty when employed on Search and Rescue operations that can skew that judgement and lead people to accept higher risks because lives are at stake.
The trouble is, if you have never trained in those conditions, it is easier to be optimistic about your chances of success because you don't realise how hazardous the environment you are about to enter actually is.
As inputshaft highlights - a risk-averse management structure doesn't actually make things safer....far from it because you then allow inadequately trained crews to put themselves at greater risk - unwittingly because they don't really understand the risks - than if they had been exposed to those risks, in a controlled fashion, during training.
