I was sitting alone as I often do on summer nights against the wall of my house on the tile terrace overlooking a small lawn and a wooden fence. I was facing west and watching stars. That night was the second time in my life that I witnessed an inexplicable celestial phenomenon. One of those fixed stars in the west, about 45 degrees above the earth curvature, moved and sort of glided down toward me and high over the roof of my house. Its acceleration was impressive and it gave out no sound at all. Just a very fast, more than supersonic-speed but absolutely silent glide high over my house and then it disappeared over the roof in the eastern direction. It was so quick and silent that I did not even move. As it was briefly flying overhead it looked more like an oval of light, an elongated teardrop of light /I am myopic and always wear specs and I realize that this always handicaps me when I watch night skies/.((NUFORC Note: Witness indicates that the date of the sighting is approximate.
