I had not really paid attention to it before, but this plane had no windows. Instead, the walls, ceiling and floor had turned completely transparent. Or so it seemed. I reached down and touched the floor and apparently it was some kind of screen. The entire interior of the plane was covered with this screen material, and it was displaying a view that made the plane appear transparent. Overhead there was a brilliant blue sky with a few puffy clouds. Beside us in the distance were other planes. Below was a remarkable city and we were flying right over it.
