Is this some kind of visual measuring charge to determine a woman's bra cup size but getting a side boob view or what ?????
She looks great and the scene is both amusing and makes its point.
I remember the episode
Oh-Yeah! Me too! Probably because of this scene: where the perv department back at earth SHADO HQ have reasoned that the best way to show Straker how the alien tracking space probe has failed and that with no way of measuring altitude/distance from the alien world you may as well abandon all hope and spend the rest of your days eyeing up Lt Ellis' LEGS!!! How very dare they!!! I mean!!!
