potentially overseas newbies with no SAR experience who will fly for peanuts
Get a reality check, will you. It's not RyanAir that's taking over; it is an established company that was doing SAR professionally probably before you were born. They have, and they will, despite all the tearing of sackcloth and knashing of teeth by several of these posters, be able to carry out this task on the basis of skill and experience.
Plus, they will have some decent kit to do it with.
