At about 20h30 observed a yellow to white light at about 4000 meters moving silently from east to west heading roughly from Sandton in the direction of Hartebeespoort estimated to be traveling at about 9,000 k`s per hour. The light stayed the same from front, overhead and rear. First time I have seen anything like this. I am an ex pilot.
