Rolex Double Red Sea Dweller
A Close Call
In May 1974, I was living with three other aquanauts for two weeks at a depth of 100 feet in an underwater habitat named La Chalupa. We were 10 miles off the southwest coast of Puerto Rico. The primary purpose of this mission was to test new excursion diving procedures for the first time in the open sea to depths of almost 300 feet.
We were breathing a nitrogen/oxygen mixture while
in the habitat and air for the dives. The air passed through a 700-foot
hose from the habitat into our special helmet. While on a dive,
aquanauts used separate hoses and carried twin scuba tanks for safety
backup.
Prior to the mission, a couple of friends, who were also navy
divers, taught me how to ditch the helmet in the event of an emergency.
