Seems as though what Maun really needs is for the companies to wise up to the joys of employing a stable work force. Maun could tout itself as the last resort, the final watering hole, the place where old pilots, who probably started their careers in the bush decades ago, come to fly before they die.
No one with less than ten thousand hours need apply and if you can't navigate by Doppler or Loran, you're no use either. Not that the aircraft have those kits anyway but it's a measure of the man.
That way, there'd be no low time hour pilots in Maun at all, only Captains and Commanders, just like Bristows Do 328 operation in Nigeria and the grand piano in the compound.
