Getting out of harness is as vital as getting into it when a parachutist is coming down over water. At the naval air station at Corpus Christi, Texas, the men are taught to free themselves from the chute just before they splash. On the way down, the chutist begins by unfastening the chest strap while balancing himself on the cushion. The tubes seen on the flier’s chest are not part of the parachute harness but lead to the rubber life jacket. This he inflates by releasing carbon dioxide from metal containers in the jacket. He can use lung power to add more air when the supply in the gas flasks is exhausted.
