fireflybob,
Who said anything about going back to aviation afterwards!!??
Well liquidhockey, who started the thread, did. He specifically mentioned it as being something:
worth looking into if you are struggling to save up the money for self funding
This is a forum for people who want to become commercial pilots - not one on which to discuss jobs in general.
As for ethical, presumably if a person (someone who did want to return to aviation) went to a job interview for a train driver job they would have to give reasons as to why they wanted to be a train driver. Saying 'I thought it would be good way to earn money and save up for my commercial pilot's licence' would probably not go down so well if they were investing in your training. The only other option therefore is to lie, and keep your flying aspirations from them. Hardly ethical,
TB
PS. What is 'the Shuttle'
