Another post on the same forum:
I used to be a reservist with the RAF Search & Rescue, in my other time I used to be a stage manager / stage crew. After my Sqn was disbanded I carried on crewing and was asked to stand in as the safety officer for one of the theatres I worked at after the SO had an accident and broke his leg.
Does that help? Didn't know we had Resrvists on SAR apart from some FTRS. I stand to be corrected...
