Hello
I'm former heli crewman (now comissioned) and would never regret it. Fantastic job for most of the time. I think we all live for 10% of the job anyway.
I am pretty sure the age limit is 32 but they will take you up to 35 "in exceptional circumstances". Depending on the climate, this could mean that you have a pulse! Currently, they are desperare for AA and have just launched a massive ad campaign, and so perhaps still being warm could be good enough.
You should stand a reasonable chance due to your former time in. They WILL try to push you WSOp so don't give them a sniff if you don't want to be flyng around in a beige tube.
As for Admin (Trg) then it's up to you. If you have the quals, you would probably be better off in the big wide world. Again, they will probably attempt to push yu in to a comissioned gnd job if you have the quals. Stick by your guns. Don't believe anyone, I repeat, ANYONE, who says you can change once you are in. They lie.
As for comissioning as rearcrew, age is already against you old chum, unless you are bloody brilliant. Even then, you may be seen as a threat by the more senior ones...
Good luck whatever happens <img src="smile.gif" border="0">
