Unless other books are examined, it would not be possible for the average reader to assess this book from a historical context. It would also be helpful to look at German language books about this subject. Although the author rightly points out atrocities committed by some in the German rocket program, it is difficult, in some cases, to know all of the details. Even after all this time, what might be called "fair and balanced" accounts might be difficult for some to believe.
Putting the author's own bias aside, the book chronicles a project led by men in the US Intelligence and aviation communities with purely practical goals in mind. The fact that it continued after its official closure shows how critical these former Nazis were to the United States. As a side note, I should mention that the Russians got their share of rocket scientists as well. Many people are unaware of how many worked in Peenemunde during the war.
In 1950, a two volume set of books was published titled German Aviation Medicine under the auspices of the U.S. Air Force. It should be pointed out that a title like, Aviation Medicine would have been descriptive enough. Its authors were some of the same Germans that worked for NASA.
The author also covers the effect of former Nazi technicians arriving in Argentina and other South American countries to continue their work there. The following chapter paints a disturbing picture of Paperclip scientists being involved in experiments in the United States with dangerous and mind altering substances. She also reveals that Austrian scientists were being recruited.
The book closes with chapters devoted to ferreting out information about any criminal wrongdoing by members of the rocket team during the war and the implication that America was too influenced by Nazi ideas and thinking. This is a very dubious claim. The British stated at the end of the war that the V-1 and V-2 were necessary for their very survival. Indeed, this technology was not just about getting to the moon but was the genesis of ICBMs and current cruise missiles. There was no time wasted between the Americans and Russians; everyone grabbed whatever they could, nailed down or not. And everyone raced to arm for the next possible conflict.
Though the author condemns those in charge of bringing Nazis to the United States in violation of the law and moral norms, the fact of the matter was that the Russians still had their armies in Eastern Europe and fears of an early conflict were quite real. The Russians had added captured German jet fighters and bombers to their inventory. They also had captured V-1s and V-2s. Estimates regarding the development of the first Russian atomic bomb were being drawn up.
