The C47 TP Dakota coming in to land has replaced most of the old Douglas DC3 piston engine planes used by the SAAF.
In 1994 a project was launched to modify all Dakota aircraft to turbo prop status. One of the features of the C47 TP is an extended the fusilage. I believe that the large window on the starboard side is the toilet window.
The cruising speed of the C47 TP has been increased from 250 to 330 kph and their range bas been extended from 2500 to 4000 kms. They have an increased payload of 1000 kg.
The grey and white livery indcates that these are used for maritime patrols
