That's a good review, but you should read Angle of Attack, the book. It's short, and very well written, lots of aerospace engineering details. I was a stress analyst at Martin Marietta in the 80s, there were no discernable technical errors in Angle of Attack.
This was a satisfying article emphasizing the engineering ingenuity to build Apollo. I read the book awhile ago and remember a scene not mentioned in the article about when North American went to go make their formal pitch to NASA for the Apollo command module. When the arrived in the room they realized their slide projector had the wrong adapter for the outlet. Panicked they looked for a solution to no avail until someone had the idea to just cut the cord and stick the bare leads into the wall. Problem solved; and they won the contract. Fun book.
