Sadly, a similar problem afflicts us maintainers as the years go by. It's a year or two since I last wielded a spanner in anger, and a good few more since I wielded my first on XL392, a mighty Vulcan in the factory at St Athan.
30 years on at least I can still see real live aeroplanes out of my office window and on those days when it is freezing cold and wet thank the Lord for small mercies.
