In February 1942, aerospace doctors Zygmunt Rascher, Zygfryd Ruff and Wolfgang Romberg conducted a study on the issue of high altitude flight at Dachau Concentration Camp. Over 200 prisoners were used in these experiments and about 80 of them lost their lives. The document begins with the reading of the letters by Zygmunt Rasher to the Reichsführer on experiments; They contain accurate descriptions of death and autopsies. From the documentary we learn that the first man who crossed the space was an anonymous merchant of Jewish nationality - it was in Dachau, 19 years before the Soviet space flight Yuri Gagarin.
