SAA had its Viscounts 58-71
I'm a regular at CPT and apart from the mountain, nothing looks familiar! I have however wandered through some old brick buildings whilst flying with Good Hope Flying Club (by the Safair hangar) and wonder if these are the same buildings as pictured?
Also, is that Athlone power station lurking in the back ground? I believe that was built in the early 60's, with the towers demolished in 2010
