As much as I would hate to upset any keen and thrusting health and safety rep types! If a mature and sane adult volunteers to accept various unknown, potentially dangerous, tasks for a substantial cash payment (and possibly a revitalised career!) why not let them do it without complaint?
Secondly, if I was stupid enough to get myself into that situation, given the choice of eating grubs and spiders or jumping out of that helicopter over the water, I would pick the helo jump!
Saying all that, I would be asking a fair few questions if I was told to fly the machine that people were jumping out of!
