    When the U.S. submarine Squalus became disabled at a depth of 56.5 m, a cylindrical chamber was lowered from a ship to rescue the crew. The chamber had a radius of 2.18 m and a height of 3.88 m, was open at the bottom, and held two rescuers. It slid along a guide cable that a diver had attached to a hatch on the submarine. Once it reached the hatch and clamped to the hull, the crew could escape into...
