A. At the beginning of April or in the middle of April, Rascher told me for the first time that he was performing experiments with slow ascension and that he had attempted to work with Fahrenkamp but the work had been interrupted when the latter was sent away. I said that had nothing to do with our experiments and was quite unimportant and uninteresting from our point of view. He admitted that, but said it was a specific question which especially interested him personally and which he had to work on. I did not see these experiments, which according to records here lasted 8 to 10 hours. He probably always performed them on the days I was absent because these 8 to 10 hours would have interfered considerably with our experiments. He expanded these experiments and performed time-reserve experiments at certain altitudes to test the adaptation which he had been testing before in the slow-ascension experiments. This was an experiment in which the subject remains at the same altitude, in contrast to the falling or sinking experiments where the pressure is constantly increased, that is, when the altitude is decreased. As his interim reports show, he extended these experiments to high altitudes and the time reserve was studied either with or without oxygen. The suggestion for this in part came obviously from other work, such as that of Dr. Kliches. I sometimes observed these experiments. He performed them correctly; he watched the subjects so that there was, in itself, no objection to these experiments. The only thing was that they interfered with our experiments from the point of view of time, and Rascher’s lack of punctuality was a much greater annoyance in this respect. According to the documents, as well as the witness Neff, Rascher apparently had deaths in these experiments. The first deaths were evidently unexpected. In these unexpected deaths the electrocardiogram and the autopsy findings, together with his reports, apparently gave Himmler the idea that these experiments should be carried on further, and in addition that Fahrenkamp should be called in to extend them as far as possible scientifically. The fact that Himmler was covering them apparently induced him in my presence to perform experiments which were dangerous, and in which deaths occurred. The fact that I had been present several times at previous experiments brought about my presence at that fatal experiment, too. Q. Did you not think it unusual that during an experimental series which you and Rascher were to carry out together, Himmler suddenly gave Rascher orders for special experiments?
