As I said, it doesnt matter where people come from as long as they are competent in their job.
RAF is not the only institution that knows something about SAR. There is f.ex very good AWSAR coverage at several Norwegian oilfields, and the service has been there for many years. Paid for by the oil companies, but frequently used by the Rescue Coordination Centres. This is not the same as Jigsaw.
The service is now being upgraded with EC225's with all the goodies installed. Many people doing this job are not from the military. I am though, and after 30 years offshore I am humble enough to realize that coming from the Air Force did not give me all the answers. There is no difference in quality if selection and training are optimized.
