I think down at Swanwick with the such reliable system we've got, even an hours walk out would go very noticed. I for one wouldn't want to even sit down knowing there is no Systems or Engineer support in the room next door. It compromises safety too much. One frequency down, loss of radars, EDDUS link failed again (whatever it does), workstation problem, bandbox/splitting problems, or the inevitable NAS failure would have too many safety implications not to be fixed immediately. You'll probably find that if your going out to the gate, we'll be bringing the coffee and banners.
