During the cross-examination by the defense counsel of Dr. Romberg, the witness Vieweg explained his expression, the “10 exhibition patients”. (_German Tr. p. 485._) The 10 selected patients who were used for the high-altitude tests had been accommodated in a special room and had been well nourished; they had been exhibited, and they had been presented to Himmler during one of his visits. Himmler made them big promises; if they survived, they would be set free * * * these 10 patients had been drawn into the experiments * * * they had told him (Vieweg) that they were very exhausted by the whole affair, but as far as he could remember “they all survived” (_German Tr. pp. 486, 489_). On being questioned the witness Vieweg repeatedly stated (_German Tr. pp. 486, 487, 489_), that as far as he could remember Dr. Rascher had carried out the experiments himself. The only thing Vieweg could state about participation of “Luftwaffe officers” in these high-altitude experiments, was that some Luftwaffe officers “had also been there”. But he could not say anything about the actual participation of the Luftwaffe officers. From the description on page 501 (German Transcript) these two gentlemen of the Luftwaffe certainly were not identical with Buff and Romberg. He himself (Vieweg) had only talked with these 10 official experimental subjects, the so-called “exhibition patients”, but not with any of the other experimental subjects. He himself had never observed that these other prisoners were used for high-altitude tests, but he had been told about it frequently. Vieweg repeatedly stated that the 10 official experimental subjects had still been alive at the end of the experiments (_German Tr. p. 489_), that no deaths had occurred among them. So much for the statement of the witness Vieweg. It is, of course, unreliable because it does not establish a clear distinction between the high-altitude experiments authorized by Ruff and carried out with the cooperation of Dr. Romberg, and other experiments in the low-pressure chamber which Rascher undertook by order of Himmler, without the authorization or previous knowledge of Dr. Ruff and without the cooperation of Dr. Romberg. This distinction, which is of decisive importance in judging this case, only appears in Vieweg’s statement insofar as the 10 official experimental subjects (the so-called “exhibition patients”) were exclusively used for the first experiments (Ruff-Romberg-Rascher), whereas other prisoners were used for the other experiments (by Rascher alone). Of course, the significance of this distinction was not clear to Vieweg at that time and could not be observed by him because Vieweg did not know anything at all about Dr. Ruff’s activity and since he did not know anything at all about the agreements which had been reached between Dr. Ruff and Dr. Rascher.
