This is an incredible book, narrating the larger than life story of Kelly Johnson and Skunk Works - the Lockheed division that designed and produced fighter jets during the cold war.
John Dean definitely put in a lot of work. The Impossible factory is extremely documented, digging into the details of engineering and producing those mythical airplanes.
You will especially love the book if you are an engineer, a project manager, or an airplane nerd (or all three). I personally loved learning about all the problem solving that goes into designing, testing and producing airplanes as a defense contractor.
For instance, flying at an extremely high altitude requires a different type of fuel, which had to be especially engineered by Shell. Pilots needed special suits to make sure their blood would not (literally) boil. And of course, fighting the bureaucracy in order to deliver those exceptional airplanes in due time required political and managerial skills that were ahead of the time.
All in all, a fascinating book, written by a passionate author who really tried to understand aerospace engineering. I regret not having access to the (now declassified) blueprints and manuals, but the book ends with a promise to set up a website in order to share the sources.
Thank you so much NetGalley, Dutton and of course Josh Dean for sending me an ARC of this book. I learned a lot and cried a bit. So long, Kelly Johnson.
