Newscaster,
Read my post 66 above. A large fraction of the GSS pilots are not going to find anything. Those under 50, especially if they have sufficient command and or training experience will be fine. The rest of us, and that is a considerable number, are having to come to terms with the end of their flying careers. And not just the age 60+ BA retirees. Guys in their early to mid 50's who do not have pensions and nice memories to fall back on.
Aviation in the UK is now an option for the young and the wealthy only. Experience not required and in fact a definite disadvantage. A willingness to work for nothing or on short term minimum wage a must. Plus sufficient spare cash to give away on a punt known as a self funded type rating.
This short sightedness is eventually going to bite certain companies on the backside when their entire workforce has bogged off to the Middle east and they try to run their services with school leavers. Good luck. Unfortunately this is unlikely to happen in time to save those who might be able to offer a bit of experience and perspective.
Enjoy your aeroplane spotting hobby. As long as you don't get conned into making it anything more than that, you will have found the secret of a happy life.
