I dont know the way in the plane world but young people wanting to get into flying helicopters often take on a job with heli training schools. This work generally involves cutting grass, cleaning helicopters, getting coffee etc, and often for no pay.
Instead they are given free hours flying. A friend of mine started at 14 yrs old and is now a flying instructor aged 21 with the same company. Not bad. And all free. Its jsut a case of being keen and persistant. When i say persistant, i dont mean annoying.
