Funnily enough none of my kids wanted to fly solo and they never asked to join the club. I think they just liked to be able to brag to their mates that they could fly an aeroplane.
My youngest actually flew once when he was four. We couldn't locate the ballast weight for the Capstan (some idiot had left it in the cable towing truck). He went up as the ballast with one of my mates. He loved it. Highly irregular, but that's one of the beauties of civvy gliding. Between that, and his twelve year old sister who liked driving round the peri track in my car with her siblings on board. She taught herself to drive in that car. Mind you it was an automatic, because I doubt she could have managed a geared car.
