This has to be the cleanest explore I've ever done and one that's been on my list for a very long while.
In fact it was so clean that I showed up in a black suit, black shiny FBI shoes and was for all intents and purposes a bona fide business customer, in fact there's no way you would get in here without the correct 'credibility props' and it certainly makes a change from wading around in cold, deep, stagnant water, human faeces or crawling around in deep, musty bunkers, hell I even got coffee and a name badge :-)
Photography up there is a witch though as the outer section of the room is rotating relatively fast, sunlight is coming through from all angles and reflections from other panes of glass in the structure are damned hard to avoid (in fact I've binned 20 shots already)
