I don't see anything about any change in the way the service is paid for.
The age of the existing equipment means a change had to be made.
The current search and rescue service seems to be something that just growed. In the 1980s, a friend of mine was on SAR as a navigator. He said, rescue missions were a good alternative to training.
Much better to pick a real person that have to collect a bale of straw.
Clearly, the expansion of leisure activities means the demand has risen and it has had to become a full-time service. That means the SAR qualified staff aren't available to go off to pick up downed airmen in a war zone.
The other thing my friend said was that most pilots quit soon after finishing their SAR stint because normal flying didn't satisfy them after the buzz.
