When organising a staff ride last year I got in touch with the people who now look after Upper Heyford airfield, Heyford Business Park. Through some very helpful people I was able to get access to the old WOC; it is remarkably well preserved with the last tail no / crew / wpn allocation tote boards all still marked up. Overlooking the 'pit' is the Nuclear release room; quite chilling really - you can even recreate Crimson Tide by flashing the 'EAM' sign on/off and pick up the 'red phone' to NORAD (no, it's not connected...). They also have access to the old Nuclear QRA HAS site..it's a real time capsule.
PM if you want any extra detail.
