Context
In April 1991, the Belgian UFO wave had been over for about a year. The black triangle had become the defining shape of the era. Then a triangle was reported somewhere very different. The north-eastern fringe of Pretoria, South Africa. Baviaanspoort lies within the Kameeldrift area. Eersterust, a township about 15 km east of the city centre, sits some 7 or 8 km to the south. Over three nights, both places would report lights in the sky.
