Triangular craft in South African skies.It was late in the night and we returned home after visiting my brother in Hartbeespoort. Very few people were on this road that passed through the countryside. I got a strange feeling to look out of the window and then I saw it. A huge, black triangular craft hovering, I estimate, about 300 feet above the ground(not entirely sure) It had three red-orange lights on each point of the craft and one bright blue-white light in the middle that shone on the ground. It looked like a searchlight. The object just hovered on one place for a while. when we passed it, it moved in a circular movement across the road behind us. I did not hear any sounds, but the thing gave me cold shivers. I felt kind of connected to the thing in a way. My parents, although freaked out in a way, thought it was probably some millitary craft. I only took my eyes off it for a few seconds, but when I looked back it was gone. Nothing in our car failed or went haywire. I will never forget it.
