Arm out the window, ever been involved in a sporting club and fallen foul of the managing clique? I know far too many people who have been involved in gliding since 1960's who have given up (and they still own gliders) because the regulatory burden imposed by the GFA - often quite independently from CASA's strictures - gets in the way of flying, something that they have done quite safely for decades. So what happens is those who want to be amateur regulators build paper road blocks to the growth of the activity resulting a decline in membership over the past 30 years of 50% and an even larger decline in hours flown. Have a look at the age profile of the gliding clubs and I seriously think that gliding will not exist to any meaningful extent with the next 10 years. The model is broken and unattractive to those living a modern life.
