Just FYI. Almost every launcher that offers commercial services has such a user manual. I was involved in preparing one such manual. A collection of these manuals can be quite entertaining for 5 year olds. You should be able to easily find them from the websites of the respective companies or agencies.

Thanks for the tip. I only knew about old manuals of the space shuttle.

NTRS is an amazing resource for that:
