Oh JimF, do back off a bit and relax old chap:
1. You're on an aircrew forum.
2. The majority of SAR jobs don't involve MRT.
3. Even when MRT are involved, they're not part of the operating crew; not even supernumerary. Passengers with good intentions.
4. How do you think we manage to cope winching somebody off a trawler? Pitching seas and, heaven forbid, the little Frenchman hasn't done his Stage 1 drills!
