Mir incidentIt was in the early evening, and I was standing with my brother and friend on the front step of his house. We were looking up to our left to see the Mir Space Station coming into low orbit over our region of Cornwall. I then just happened to look over to my right and I saw a spherical white object moving slowly towards us, I pointed this out to my friend and brother and we all agreed that it was not any man made craft as it produced no sound and had no wings or tailfin. Within a couple of seconds it turned 90 degrees and sped away from us. It was gone within 3 seconds. At the same time as this object was going away from us, a Sea King was flying in the same direction.
