Bigger than a G-string

Professor Wilbur Rounding Franks at U of T's Banting and Best Department of Medical Research developed the Franks Flying Suit, the first anti-gravity G-suit which was first used in combat during the North African invasion in November 1942.  He began his research by using water to keep blood from pooling in the lower parts of the body, experimenting on mice surrounded by water-filled condoms.  Eventually, the use of air pressure proved more successful.
