Just a suggestion
Can I make the point that although talking to the directors is a good idea, your time may well be spent a bit wiser talking to as many current and ex-cadets as you can. You will probably get a better insight into things like life in NZ, the flying, the instructors, the groundschool etc etc from them, than you would from the directors of the company.
Get as much information as you can, as these people are there to help and will (hopefully) tell it as it is. Any wings cadet will tell you it's not all rosy, as I suspect the directors would too (hopefully...), but the guys and girls who live and breathe 'CTC' everyday for a year and a half or so, are in my view, a far better source of info.
