You should have read this before you made the comment that the U.S. could not have gone to the moon without the German Scientist. Repeating my previous post both the U.S. and the Russians used captured German rocket scientists on their programs. Both countries were in a race for a dependable intercontinental missile to be used as a weapons platform.
...I did read it, but did YOU ?? Sergej Korolyov was NOT a German, neither any of his colleagues...
Korolyov used Germans to reassemble the soon to be obsolete V2 and its Russian successor, but no Germans had involvement in the R7 rocket program, nor the Sputnik project. The top dogs of German rocket engineering lead by Wernher von Braun fled into US conquered area because they knew the Russians were coming to their base, and they felt they were better off in US custody. When the land was divided into east and west, US teams had already shipped all the important stuff behind the later iron curtain, so the Russians had the base, but only the lesser engineers, and not the premium technology..... the US held the German top dogs back, first insisting on letting Americans do the job, but after failure let the Germans develop the Saturn rockets and the Apollo program. Von Braun led the US space program from 1960-1970. So, while both programs were based on German technology, it was between Russian and German designs...

As said before, i like to hear inside stories and facts over propaganda from either side...

And i have deep respect for the Russian engineers that had all odds against them, imprisoned, under fear of being shot for failure, etcetera. Nonetheless they were mere slaves...
