boy it is sure nice to see all those from the silent service making themselves known. i am in good company.
the deep cesa is not difficult. the olden days of j valves forces many including myself to learn on the fly. i did over 70 because of a j valve and used a co2 horse collar for oisitive bouyancy.. i also believe the uss los angeles did one from greater than 600 a year or so off of washington state. a total of i think 3-5 made the trip to the serface. tha canadians years ago would do it once a year 50 ft deaper each year. (one person in the navy not all) and in the mid 70's they were at 650 feet. i believe they were in a fully enclosed suit. there is more problem with ruptured ears than lungs. the corpsman fixes that before locking into the escape trunk. picture yourself leaving a perfectly good submarine at more than 2 football leignths deep in rebreather land, to find yourself on the serface waiting to be picked up. and we are talking the hazzards of 100 ft and no options to pick from but up.
