Liftoff is an an excellent book. Recommended for anyone interested in SpaceX or space in general. The writer's style is a bit dry, however it's a fun story regardless. The gritty insides of the early days of SpaceX are both what you hoped to read about and sort of crazy remarkable (like the elaborated story about the imploded Falcon 1 that was being transported by C17 and ultimately saved SpaceX from oblivion). People risked their lives to make SpaceX happen.

It reminds me of a bigger company version of Masters of Doom. Same hacker ethos driving those early days.
