One cadet has already expressed his intention to leave and work for his father once his contract period expires (If it hasn't already done so.). Seems the airline life isn't as easy and glamourous as he envisioned....
I met one of the (PDI) SAA cadets not too long ago. He trained in Australia, obtained his CPL and then resigned to work for his father, who is not even in the aviation industry.
He still has the posters on the wall, model planes on his desk and loves aircraft, but I'm not sure why he left?
