This book is for the fans of "The Greatest Generation"-type books. Both Patton and Macarthur got cinematic limelight, but we hear less about Admiral Nimitz, and even less about Doolittle. This book completes the Temple of the World War II Titans.
As I read, two things impressed me. First was Doolittle's down-to-earth and conversational style. I felt like he was sitting next to me, chatting on the on the golf course, and just reminiscing between tees. The second was the drastic changes in flight that occurred during his fourscore and ten years. He saw aviation from the Wrights brothers to the Space Shuttle. All in one lifetime!
I was also surprised how involved he was in developing aviation technology--he had a hand in the modern cockpit instrumentation. Things such as the artificial horizon, radar, and the dashboard layout came, in part, from him.
Other surprising things were behind-the-scene info Billy Mitchell, supply problem in WWII, and also the three friendly fire incident he was involved with. It puts a perspective on the current conflagration.
In order to round out the book, you need two supplementals. The first is to see "Patton." Doolittle provided the air cover for Old Blood and Guts, and the book contains many references and quotes from Patton. Yes, he was accurately portrayed in the movie, except for his voice. Doolittle mention he had a high, almost feminine quality to his voice, which explains his potty tongue.
The second is to read "Catch-22." Yes, Heller is writing about serving under Doolittle. As I read, I wondered if Dreedle=Doolittle.
This book is even-tampered in its approach to war. It is not as idealized as John Wayne, but did not swerve into the demoralizing MASH or Platoon.
