Mallardpi,
The CG machines already do alot of work over land.
They are already manned by a significant number of civvie trained crews up to the highest level.
The CAA are already involved - how do you think Bristow's and CHC have been providing civillian based SAR since the 70s?
There is already significant commercial competition in the market place to keep prices down.
As for experience, I think you will find that some civvy sar copilots have more years SAR experience than some military SAR captains, virtually all the civvy crewmen have a full military service behind them plus the civvy world since leaving and there are enough ex mil instructors in civvy street to allow training for NVG and any other relevant specialisation.
There are many on this forum who have no confidence in the civvy system. How many of them will be swallowing their "pride" and knocking on Mr Bristow's/ CHC/ Bond's door looking for a job when the leave the mob?
