Stationair8 Who else flew the SP
South African Airways had several and I remember being on the inaugural flight (as SLF) from Cape Town to London in the "Matroosberg". Probably 1978
On the right hand bulkhead as one entered the aircraft was a plaque commemorating the delivery flight Seattle to Cape Town non-stop.
It was intended to avoid the stop in Sal Island for the SA to Europe Routes.
