I'm with Crabb on this.
What's the point of sending out an SAR pilot on an SH job. He doesn't know the business, doesn't know the aircraft, he's just a liablity. He is more likely to lead to the loss of an aircraft and other more valuable members of the crew. If you are going to have to train him to do the job then you're just as well employing civilians. Dangle a twin turbine heli course, lots of hours and £30K tax free and there would be stacks of PPL(H) and hour-building CPLs queuing up.
