Hi Rick - would a reasonable extrapolation of the thickness of the hull come from a combination of the view you provide (below) and observation of the thickness of the window frames from say, "Ten Forward" or the "briefing room" scenes from the show? Or are those rooms with windows just happen to have unusually thin hull sections?
