The N-1 was the USSR's answer to the Saturn V. BBCnews has this report revealing previously unknown aspects of its design as well as new pictures. More than 90 of the N-1's engines were recently sold to an American company for encorporation into a new rocket. I have heard rumors that there are a lot of spare Saturn V engines as well, especially third stage engine, but because the program was in such a hurry much about their operation was never written down and now nobody knows how to safely operate them anymore.
