Excerpt
An excerpt from Jacques Cousteau, 1953: To halt and hang attached to nothing, no lines or air pipe to the surface, was a dream. . . . From this day forward we would swim across miles of country no man had known, free and level, with our flesh feeling what the fish scales know. I experimented with all possible maneuvers of the aqualung-loops, somersaults, and barrel rolls. I stood upside down on one finger and burst out laughing, a shrill distorted laugh. Nothing I did altered the automatic rhythm of air. Delivered from gravity and buoyancy I flew around in space.
