Don't worry, old farts have not yet taken over all the flying clubs! We sent 4 people solo last week at our gliding club, one was in his fifties, another in his 40's with a young family, another young lady of 35, and a young lad of 15.
So the new generation is still eager to fly, trouble is a lot get siphoned off into the Air Cadets, which spend more time marching and camping out than they do flying! But true enough that the retired folks have the time and the money...
