Aberdeen and Hull are not where I would choose to live, but then neither is London. At least the jobs are commutable, unlike many airline jobs, and have you investigated the start wages of airline FOs? Even BA, the holy grail of UK airlines is starting you on 50Kish.
If you have a decent rotary background and some mates you must be able to walk in to a better wage than that.
Right now, there is a police advert, and a royal helicopter advert, and that is outside of all the north sea and exotic special skills jobs around.
