In December 5 man emerged from high pressure chambers at Duke University where they had lived and worked for slightly more than three days at the simulated depth of 1000 feet beneath the sea. The object of this dive was to get. To a thousand feet as conservatively as possible to see what we found at a thousand feet and the ability of our people to perform useful work and survive. We brought him out on a very conservative schedule which Dr. summit developed. We were not trying to raise the bottom in a race to the surface we were trying to get down there safely and see what it was like there without handicapping the people before they got there. Navy Captain Eugene Mitchell was very pleased with the results of the test dive in which men were subjected to more than 30 times normal atmospheric pressure. In a moment we'll hear more about the saturation dive.
Challenges in education presented by Duke University. Here with today's feature is Charles Bronson. Never before has man been subjected to such pressure for three days. Although there have been a few other dives to the 1000 foot level they have been bounced after only a few minutes. Dr. Herbert Saltzman director of the Duke hyperbaric unit comments on the performance of the man tests performance indicated remarkably normal function and capabilities. All tests are limited to the conditions under which they are performed. But three of these men performed exercise up to approximately 70 percent of a maximal effort and during the period the period of time that they sustained this effort their performance was very
similar to that observed at the surface. The men three from the Navy's experimental diving unit and two civilians representing Duke University were subjected to several types of activity. We just watched these men perform. Very. Skilled tasked. With excellence will watch them perform heavy labor with excellence. We watch them meet unscheduled tasks not anticipated prior to with the same facility that these problems are. But with that the surface navy captain Eugene Mitchell speaking at a news conference made these remarks about the simulated deep sea dive. I think that certainly we could not have picked a better place to do it. We have the capability to do it in our own facility but we don't have the tremendous tremendous medical backup and scientific investigative talent which is
available here at Duke University and that is the reason that we chose to do it. The reason for our interest in going to a thousand feet follows from our experience earlier this year when we defined a group of people some of these very lads to the Canary Islands to be prepared to dive 2000 feet if we found the scorpion at a thousand feet. We had no confidence at that time that we could reach a thousand feet or perform useful work a thousand feet. But if there were if we had found this submarine there we would have given it a try. You have to do what you must this time but it's far better to do it under controlled conditions. It was then that our discussions commenced with Dr. Salzman about the prospect of doing a joint dive with the university they would get massive amounts of medical data. We would get the operational experience. So I'd like to summarize all of this rambling by saying simply we are well pleased with the result because we have a much greater confidence
