You mean, the book that wasn't about a Zeppelin? As in, an aircraft made by the Zeppelin corporation. The British never learned how to make dirigibles[1], the Americans never learned how to operate them; all non-German airship projects were failures. That's why Zeppelin became synonymous with "rigid dirigible airship". Because all other projects failed. [1] R100 was a good design... but it was scrapped because of politics, and never entered service.
