As someone who was a winchman many years ago, I would agree with No Vote Joe that you should give one of the flights a ring, and go spend some time with them.
I'm sure the course will have changed since I did it, but I can tell you that it is, without doubt, the most satisfying and rewarding job that I ever did in the RAF.
Hard work, and lots of bu££ering about, but a job second to none!
best of luck with it.
