Arend III,
There are no AN-12's flying freight in South Africa.
There are however the only two former Soviet era Antonov 32's ever legitimately registered in South Africa on the ZS register belonging to Valan Air that indeed performs such flights.
Valan Air is a fully and wholly South African company.
If you wish to berate them as a South African company flying South African registered AN-32 on commercial operations in South Africa, think how other aircraft owners in countries where ZS registered aircraft fly, must feel.
The TransAfrik C130,s like their 727's, were scrap. Who are you to judge any of the contracted IL-76's, have you inspected and scrutinised them (CAA does so regularly), seems to me that they are getting the job done cause even Safair contracts them.
What is wrong with South Africans, why do they always think that everybody else except themselves or their specific company are "fly-by-nights", uncapable and insufficient. Is it an inborn thing? Sometimes this skew logic and bitternes is amazing. Instead of trying to walk over others bones look at your marketing and just simply raise your standards to do a better job and obtain contracts and flying on merit.
Get a life.
