In Summer 2010 I was in a London Park it was a very sunny day with a few clouds. I looked up and saw what I thought was a plane. It was reflecting the light as they do and I thought what is that? It went behind a small cloud and did not come out of the other side and I just went "What???" It was like something vanished before my very eyes, imagine seeing a car driving down the road and then for it to vanish - that is what happened. I believe it was a UFO! It was not a satellite because that would have come out the other side of the small cloud. Nothing came out of the other side...
I have watched this video and I believe there are UFO's. Anyone else had similar experience?
