Rod, don't forget to mention they can start flying from age 12 - 13 IN GLIDERS. Acquiring the basics at low cost; start of many a flying career. And go solo at 14. I have introduced quite a few teenagers to flying at my club, and have served for years as Child Protection Officer.
Around the midlands there are many gliding clubs that welcome young people. Husbands Bosworth, Stratford, Shenington, Bicester. Usually offer special rates.
Alas, ATC has managed to mismanage their aircraft, so not a lot of opportunity in the last 3 years for youngsters to fly in ATC.
