Moon Lander: How We Developed the Apollo Lunar Module

Who knew that the detergent you used to clean the cloths mattered when you wiped down the weld in a titanium tank?
Or that removing contaminants would weaken a propellant tank?
Not me but I do now after reading this book.
I think the Apollo program was the greatest engineering feat in human history.
I've been reading a bunch of books in honor of the 50th anniversary of the first moon landing.
There was a little too much about org charts in this book, but enough actual engineering stories to compensate.
The lunar module is my favorite real spacecraft and I'm glad I read this book.
