In my days as an active bush walker in the NSW Blue Mountains every injured person was carried out by volunteers of the Federation of Bushwalking Clubs S&R section.
Now days virtually every person is lifted out by helicopter.
This is far better as long as affordable and doesn't result in unnecessary accidents and fatalities .
I love helicopters but they often result in extra risk than being on the ground.
When the person about to be winched is given no choice ( when there is a safer alternative ) it's important that they are not exposed to unnecessary risk.
