Would You Believe They Put A Man On The Moon, page-171

Plenty of leaks. Plenty of people murdered by the establishment also to shut them up. Probably the biggest, but subtle, leak which influenced a generation of American engineers was the book "Vector Mechanics for Engineers, Statics and Dynamics" (1972) by Ferdinand P. Beer and E. Russell Johnston. If you understand the material and work the exercises you'll definitively prove to yourself the moon landings were faked.

The spacecraft was way too small. Too many inconsistencies in the claimed sizes, masses, specific impulses, and so on. At least Kubrick when he did the 2001 movie had at least plausible spacecraft. Actually, if it is ever done for real, it would probably look alot like what he portrayed.
