What is a Virtual Window in an aircraft?
They are basically window-shaped screens, displaying a feed from a camera so the middle aisle suits (where the alternative is a wall) passengers can enjoy the "view".


  The most interesting thing to me are the virtual windows. First Class passengers in the middle suite will have a set of “windows” like everyone else, only theirs will show images from an outside camera.
