Whenever you watch THE EMPIRE STRIKES BACK , do you get the feeling that you've seen bounty hunter Bossk's costume before?
Well, you have, (if you're an uber nerd). It was recycled from a spacesuit seen on a 1966 episode of DR WHO.
and Dr Who, 1968
Update: I've recently learned that it is a Windak high altitude pressure suit, developed for the RAF in 1962. The suit was constructed from a single layer of gas tight rubberised silk bonded to strong cotton. It was internally pressurised by air in order to achieve a higher pressure upon the wearer's body than naturally occurs at very high altitudes and beyond.
