Rockets and People

If you're into the history of the space program, have I got a treat for you. Rockets and People is a 4-volume history of the Soviet space program, written by Russian spacecraft designer, Boris Chertok.
The link above is to volume 4, which covers the period 1968 to 1974, when the Soviet Union was in serious competition with the United States to be the first to land on the moon.

I'm particularly interested in the N-1 booster program. If the last flight had lasted another 20 seconds, the program might have continued, and the history of the space race would been very different.

You can download all four volumes for free from NASA in EPUB, MOBI, or PDF.
