SHADO HQ was secreted in a subterranean base underneath the Harlington-Straker film studios in London.
As on moonbase, the personnel were predominantly female and – with very few exceptions – they were also young and shapely, wore skin-tight clothes and didn’t actually seem to do very much at all.
Other memorable female operatives at SHADO HQ included Janna Wade (Jean Marsh from Upstairs Downstairs) and unnamed operatives played by Penny Spencer (of Please Sir! fame) and Louisa Rabaiotti (the sight of whom caused Colonel Alec Freeman to comment to her, “You’re new here, aren’t you?”).
