Thing.
The flight training industry constantly needs new recruits , be it the likes of the professional airline providers or local little airfields. The training industry needs per hour fee's while the individual is training but once they are fully licensed (as far as they want to go) they are redundant as far as the training industry is concerned and they need MORE to keep going. So the hunt is continuously on, with quite frankly a lot of salesmanship and over enthusiastic false "promises". From the professional side this has destroyed aviation as a profession due to flooding the industry with pilots, and from the amateur side it constantly produces a lot of people who spend a lot of money for what?? a cheap $hit coloured book.
