Couple of responses.
If I'm being honest, I am more keen on just 'flying' than joining the RAF. I just felt that the RAF would be the best approach into it - seeing as it is actually the 'Royal Air Force'. I would love any chance to fly really, be it civilian, or as part of a job, but if it is a job, I think I would learn more, and probably fly more often (as opposed to flying as a hobby, albeit an expensive one).
Looking at the RAF recruitment pages, it does appear to be quite a serious job, in terms of being physically fit and in-shape. I don't have a problem with that, but I have a bit of a hearing problem and this may be a disadvantage.
Any type of flying, commercial or civilian would interest me - but for lesson, it appears to cost thousands of pounds for the license, then there are the plane costs etc as well. I don't think I could take it up as a hobby, as I wouldn't be able to do it frequently enough.
Further feedback/advice much welcomed.
