ASB,
It's always been difficult, and expensive, to break into this game. The determination required to suceed sometimes verged on the fanatical! Is it any wonder now, with the diminishing returns at the endgame, that a fraction of young Aussies compared to the past are learning to fly.
Ironically with the current state of the industry there has never been a better time to have a go. But you still have to appreciate the risks. You still have to be prepared to see it through. And you still have to be determined. Very Determined!
I sincerely wish your son all the best, but please make sure that both of you are fully aware of what you are getting into.
