Reading aerohead's observation about "base pressure" another idea (hopefully the last one)regarding the reduction of the drag of these mirrors. I am not sure I got the right understanding about "base pressure", but these movies will explain the idea better than words. In few words is about a mirror that becomes "porous" or "permeable" to avoid a low pressure area formed on the reflexive element.
