I was involved in the startup at Oribi in the late 70's with Magnum Airlines.The folk in Maritzburg, and the municipality, welcomed us. There have been several "tries" at PZB by Comair and by SAX, as well as a number of smaller operators. Only Magnum/Link/SAAirlink/Airlink have survived - and I am sure have prospered. It is a tricky place to fly into and even that runway has an unfortunate "hump" in it which the SAX guys will remember.
