Love that book. Sled Driver is also worth checking out. It focuses on things from the pilots perspective, but from memory the pilots had to have a fairly intimate understanding of their vehicles, so a lot of discussion of the mechanics/engineering.

Offtopic: Skunkworks, and Master's of Doom are two of my favourite non fiction books, and they both had a similar vibe. Liftoff (Eric Berger) was another. Can people recommend more books like this?
