You've been in Botswana for long enough to realise how things work here.
Why should they take the time to set up a system that has no rewards for them when they can just go down to SA and then come back for and get a validation?
Sefofane (or it was at the time) set up a CPL training scheme complete with all the theory and practical syallabus, but was then shafted by the government and they just gave it away.
Francistown has a lot more going for it than Maun. As a training environment it is perfect as the air traffic is much much less, facilities on the ground are better. And the town itself is seen as a town, rather than "a cattle post" as I have so often heard Maun referred to as.
