CAT3C, thanks for your comments.
I am aware of the reccurrence in these types of thread - I suppose it is representative of the fact that as you say the face of the game is constantly changing.
I suppose this thread is slightly different in that I'm not asking to be an airline pilot or not - I'm more interested in the careers people would now choose, with the benefit of experience. I anticipate that the answers will still be aviation related, but following a different path than they originally went for.
Thanks again.
