May I suggest considering a flying camp for your children? You can solo in a sail-plane at 14 and go on to an interesting avocation or rewarding career. I come from a pilot family and can highly recommend it, even over Scouting. Aircraft Owners and Pilots Association (AOPA.ORG) and the Experimental Aviation Association (EAA.ORG) both have youth programs. I’m sure other organizations have similar ideas. Don’t leave a hole in young people’s lives, or it will be filled by those you may not approve!
I haven't flown in years, but that experience instilled a sense of responsibility and good judgment in me at that early age, and it has paid lifelong dividends. Sadly, I look at many of the utterly clueless teens today and can't imagine them being responsible enough to act as Pilot in Command of anything. For those who have been raised correctly, however, soaring youth camps are still a great idea.
P.S. - I keep thinking about getting back into the sport. There are some nice LS-4s out there that can be had for a reasonable price.
