I highly recommend the book, Sunburst and Luminary;
<a href="http://www.sunburstandluminary.com/SLhome.html" rel="nofollow noreferrer">http://www.sunburstandluminary.com/SLhome.html</a><p>A technical pleasure and also very good glimpse into the Apollo team - working together, to land on the moon. It is a fun easy read, written by the fellow in charge of programming computer on the lunar lander. It is also a great snapshot of that time in history, the excitement of Apollo, and with the frustration of the Vietnam war going on, some protests, etc.
Just a hint - the main programmer, was an English major, and his use of the right words, were a key factor in the success of of creating an efficient and effective computer language.
