In the thread about MILSAR to CIVSAR (whatever the title was...) Crab raised issues about how Standards, Levels of Training, and other effects of the shifting of Deck Chairs (sorry.....Recliners) would have upon Operations.
He did note the On-Shift Training that was done as SOP.
When filtered for Tone....he did offer valuable content....in that thread.
HC also raises good questions about Crew Attitudes and Mindset....but does so from a Non-SAR Background.
My memory of the UK Air Regulations tells me when it comes to "Life Saving Flights" even the CAA granted a great deal of discretion to the Captain of an Aircraft and I know for a fact how it was interpreted at the small Helicopter Firm I worked for....and how many nice Watches they handed out when our Crews did something beyond normal acceptable standards of flying.
So I can see both sides of the argument going on....and both sides have valid views.
Finding the happy mix is the quest....only sticking one's neck out as far as is reasonable as it does no one any good to crash during the process of a SAR Mission.
