In this weeks show I join Devon and Somerset Gliding Club at North Hill in East Devon and get my first taste of aerotowing, my first flight in the well-respected fibreglass ASK-21 training glider and I get a whiff of competition gliding at the curiously-named 'Competition Enterprise'. And I also find myself in my first busy thermal with 5 or 6 other gliders. And this week, prompted by a question from a listener and a comment from my instructor at the airfield, I think it's time to make sense of keeping my weight under control to avoid the embarrassing risk of being grounded.
