Roooob,
I fly at Cambridge Gliding Centre, and it's true that some of us are past our first flush of youth. The airfield does cater for pilots of all ages though - within reason!
We operate a motor glider for Hertfordshire Scouts who even have their own club-room on site. They are frequently around at weekends. Cambridge University Gliding club operates fom our site, sharing our aircraft and instructors. We also run a cadet scheme for a few younger members. We have had several first solo flights of members between 14 and 16 this year.
CUGC have a picture gallery showing a few younger faces on the airfield ...
