While walking home in Alberton, Gauteng I heard a strange noise that seemed to be all around me. Hard to explain. It was like a very low deep buzz sound, but not very loud at all.
It was maybe an hour or two after sundown. I looked up and saw a triangle looking thing in the air just hovering above about a kilometer away. It stayed there for about a minute then moved up quickly and shot off to the East. It moved so fast and made no sound other than the light buzz of what seemed to be inside me. It was truly amazing.
It had no lights at all.
