The following video clip purports to show a black triangular UFO hovering over a city and transforming into a ball of light. I have no information to support or disprove the veracity of this recording. I will state that in 1996 my wife and I were seated in our garden at the rear of the property, it was late afternoon in August, suddenly the sky darkened and we looked up to see a gigantic UFO with lights shining down virtually exactly like the one in this video. The UFO we saw was totally silent and it slowly accelerated away into the distance and disappeared. I would estimate its size as being around that of a football pitch. This video shows an object very similar to the one that we saw that day.
