this book is hands down incredibly interesting to those that enjoy history, details, espionage, and the SR-71 Blackbird. this book does give an incredibly detailed view from the pilot and Cruz point of view that encompasses much more than just the cockpit. what made this book five stars for me Isn’t it could have been an incredibly tedious and monotonous task going through what each gauge lever switch and button does but both the author and the narrator do and wizard job throwing in anecdotes or stories behind many of the switches Etc very interesting
