.......you didnt need to be a QHI or in 38 gp in the early 90's!!...
.............. 2000 mil hrs and "combat ready" (or SAR "C" cat) and a mil instrument rating did nicely!
(with Air Law, Lights, RT, class 1 med and a civvie LST for your licence issue.)
Mine hung on the wall of my office inside a glass fronted box annotated;
"In Case of Emergency; Break Glass"
In the end it came in quite handy.
