Nigel,
I too am in the pharma industry and a couple of years out of my PhD. I'm pushing 30 also and cannot understand why I didn't realise earlier that I wanted to fly. Just wanted to wish you all the best. I hope to accumulate the cash some time over the next few years to make the leap from a job that although pays well, just seems to bore me. I guess it's because I know that I want to be doing something else.
Again, the big question for me is post training job opportunities. Feedback here suggests that persistance and luck are the keys. Right now I am very envious of anyone staring out on this new and exciting journey. Please keep us posted on your progress.
Best wishes,
R
