Visible crew/equipment: The "exterior" windows in Blakes 7 are a constant source of amusement. In many cases you can see the top or bottom of the board which is supposed to be the window, with empty set behind the board. Turn the brightness of your screen up to maximum and in many cases you can see that "windows" are semi-transparent perspex with light bulbs for the stars. You can often see wiring running from bulb to bulb, looped and cable-tied together, etc., through the "windows".
