Ruff and Romberg take the position that they would be most unwilling to kill prisoners in the course of an experiment. They insist that their experiments with Rascher were concerned with the problem of explosive decompression and on parachute descent from high altitudes, whereas Rascher alone worked on sojourn or a more prolonged stay at high altitudes, and that it was in Rascher’s experiments that prisoners were killed. This again is the artificial division of the experiments into the criminal and noncriminal which has already been proved to be spurious. But here again, the two self-experiments which Ruff, Romberg, and Rascher included in their joint final report as mentioned above _were experiments on prolonged stay at high altitude, a subject which they now claim was exclusively Rascher’s_. The only reason that this experiment did not end fatally was the fact that it was interrupted in time because of intense pain. Moreover, on page 11 of the final report by Ruff, Romberg, and Weltz the following is said: “This is worthy of special attention because in this case a person has fully recovered mentally at an altitude of 8.3 km. (27,230 ft.), after 3 minutes of the most severe lack of oxygen, _while in altitude endurance experiments_ at this altitude severe altitude sickness sets in after about 3 minutes.” [Emphasis supplied.] (_NO-402, Pros. Ex. 66._) Here, again, it is proved from their own report that Ruff and Romberg, as well as Rascher, were concerned with sojourn at high altitudes. Experiments, in which prisoners were killed, are reported in Rascher’s report to Himmler of 11 May 1942. (_NO-220, Pros. Ex. 61._) Some prisoners were killed by keeping them at 12,000 meters without oxygen for 30 minutes; one was killed at 20,000 meters when exposed there for about 6 minutes without oxygen. These prisoners were autopsied to ascertain if bubbles of gas, called air embolism in Rascher’s report of 11 May 1942, were present in the blood vessels of the brain and other organs when dissected under water. Some “Jewish professional criminals” who had committed “Rassenschande” (race pollution)[18] were killed for another reason: “To find out whether the severe psychic and physical effects, as mentioned under No. 3, are due to the formation of embolism, the following was done: After relative recuperation from such a parachute descending test had taken place, however before regaining consciousness, some VP’s were kept under water until they died. When the skull and the cavities of the breast and of the abdomen had been opened under water, an enormous amount of air embolism was found in the vessels of the brain, the coronary vessels and the vessels of the liver and the intestines, etc.” (_NO-220, Pros. Ex. 61._)
