 "World Without Sun", a documentary produced and directed by Jacques Cousteau in 1964 chronicles Continental Shelf Station Two, or "Conshelf Two", the first ambitious attempt to create an environment in which men could live and work on the seafloor.In it, a half-dozen oceanauts lived 10 meters down in the Red Sea off Sudan in a star-fish shaped house for 30 days.The undersea living experiment also had two other structures, one a submarine hangar that housed a small, two-man submarine referred to as the "diving saucer" for its resemblance to a science fiction flying saucer, and a smaller "deep cabin" where two oceanauts lived at a depth of 30 meters for a week.
