Civilian SAR
Civilian companies are able to keep their costs down in many ways. Use of commercial airfields, you only pay for what you use, you don't have to personally man it 24/7. Ditto transport, catering, cleaning etc. There is very little training requirement ie you buy your experience, you don't train it yourself. Staff have to be more flexible, we all wash and clean the cabs, the engineers marshall, re-fuel, ground handle, fix the aircraft and provide fire cover.
