Looks at how after the Second World War the American military recruited dozens of German scientists. Amongst them was Professor Hubertus Strughold whose subsequent development of space medicine made a large contribution in the ability to send astronauts to the Moon. However, as a Nazi doctor he was involved in inhuman experiments at Dachau concentration camp, using inmates in experiments on the effects of high altitude and extreme cold. Looks at how far the Apollo moon programme may have been tainted by Nazi war crimes and criminals.
