Saturn V Rocket Performance Report
Absolutely nothing to do with audio, but a great read for the techies.
This performance report was pulled together in the late 1960’s by Walter Haeussermann , one of the German rocket scientists who went to the US after WWII, where he settled and went on to have a spectacularly successful career with NASA. He was a key member of Werner von Braun’s team that made the 1969 US moon landing a reality. Just take a look at the section on the control computer they used to guide the beast . . .
