Everyone that knows me understands that I am the 100% USDA Grade "A" Nerd. And in keeping with that honorific I present the following to you:

The OFFICIAL Apollo Spacecraft "Owners Manual" straight from NASA

https://www.hq.nasa.gov/alsj/SM2A-03-BK-II-%281%29.pdf

That's right folks. This is the o-fish-al users guide to the Apollo Saturn Spacecraft used for the moon trip first published in 1969 and scanned to PDF in 2006.

Enjoy the nerdfest!
