Shiny metallic object, disc shaped, silent and hovering.Shiny metallic object, disc shaped. silent. hovering above our local islands. it was quite close, since the islands are not far offshore. I couldn't quite estimate whether they were above the sea or the islands cos there was a building blocking and I was driving but I know that it was somewhere in between. It was quite big, maybe 50-80 meters? Some parts of the object were darker, but they still shined, the upper part of the craft was so shiny it kind of hurt to look at. It was there for quite a while but I only got to see it for a minute or so because i was driving. Later on that day I came back to look like an hour or so later, but it had already gone.
