Rating: WORTHY!
This is from an advance review copy for which I thank the publisher.
Erratum:
There is a spelling error on the Hindenburg page. Item 04, about the keel, misspells the word 'structure'
Supersize cross-sections are not exactly supersize on an iPad, so my being only the kind of reviewer who doesn't merit a print book for review, I can only guess at how the final copy will look, but viewed in relatively small scale on a medium sized iPad, it looked swell, and would have fascinated me as a child, because I always enjoyed reading the 'how things worked' books, and especially ones with cutaways.
Starting with a pirate ship to get the saliva flowing, this book also covers the Orient Express (now that would have been useful when I wrote my parody!), The Titanic, the Hindenburg, a Sherman tank, the Saturn V rocket (always my favorite - modern rockets have nowhere near the same class that one did), the International Space Station, a submarine, a fire engine, and a host of other items, including a circus and totaling fifteen in all.
The drawings are in color, are crisp and clear, and each important part is numbered, with a key by the side of the drawing explaining what was going on in that section. It's perfect, and I commend it whole-heartedly!
