Moneyshot,
I think the reaction of some of my helicopter flying colleagues here is a little over the top. We don't all feel that way, and I'm one of the instructor wannabes who I suppose would have a right to. But I don't see your situation as much different from mine. OK, you're an airline pilot who'd rather fly helicopters; I'm a freelance researcher/writer who'd rather fly helicopters; we have at least a couple of IT consultants who post here who'd rather fly helicopters. And some of us want the best of both worlds, ie to only do it part time if possible as we know it's insecure and badly paid. It's not as though you'd be taking a job away from some poor starving unqualified 18 year old - unlikely anyway. If you got an instructing job I was after I'd be disappointed, but you'd be better qualified and that's life. It's not fair, but not much in life is. So I hope you get an instructing job, if that's what you want. And I hope you come back and read this; I tried to e-mail you, but it looks like I can't.
