BBC NEWS | UK | Magazine | Project Paperclip: Dark side of the Moon

Sixty years ago the US hired Nazi scientists to lead pioneering projects, such as the race to conquer space. These men provided the US with cutting-edge technology which still leads the way today, but at a cost. The end of World War II saw an intense scramble for Nazi Germany's many technological secrets. The Allies vied to plunder as much equipment and expertise as possible from the rubble of the Thousand Year Reich for themselves, while preventing others from doing the same. The range of Germany's technical achievement astounded Allied scientific intelligence experts accompanying the invading forces in 1945. (...) Thus began Project Paperclip, the US operation which saw von Braun and more than 700 others spirited out of Germany from under the noses of the US's allies. Its aim was simple: "To exploit German scientists for American research and to deny these intellectual resources to the Soviet Union." (...) There was, though, one major problem. Truman had expressly ordered that anyone found "to have been a member of the Nazi party and more than a nominal participant in its activities, or an active supporter of Nazism militarism" would be excluded. Under this criterion even von Braun himself, the man who masterminded the Moon shots, would have been ineligible to serve the US. A member of numerous Nazi organisations, he also held rank in the SS. His initial intelligence file described him as "a security risk".
