UFO consisted of transparent cells within a fixed shape, analagous to the shape of a mini-van. I was laying out on St. Jean Beach on the island of St. Barths (in the French West Indies), and I looked up to see a fixed-wing airplane departing from their small airport. As I looked in that direction, I saw a UFO hovering in place, above the beach toward the end of the runway. It did not move. The shape was fixed, but barely visible, and it had finely defined cells that were transparent, as if emitting an image of the sky behind it -- as I could see the clouds as they floated past, as if they were being broadcast on the cells on the opposite side, facing me. It appeared invisible to the naked eye, and I had to search for it again when I took me eyes off of it. The cells appeared to serve a singular purpose -- to transmit what was on the other side from the viewer's point of view.
