by Howard Hughes, features an unsuccessful Zeppelin raid on London during World War I. In 1934, the calypsonian Attila the Hun recorded "Graf Zeppelin", commemorating the airship's visit to Trinidad. Zeppelins are often featured in alternate history and parallel universe fiction. They feature prominently in the popular fantasy novels of the His Dark Materials trilogy and The Book of Dust series by Philip Pullman. In the American science fiction series, Fringe, Zeppelins are a notable historical idiosyncrasy that helps differentiate the series' two parallel universes, also used in Doctor Who in the episodes "The Rise of the Cybermen" and "The Age of Steel" when the TARDIS crashes in an alternate reality where Britain is a 'People's Republic' and Pete Tyler, Rose Tyler's father, is alive and is a wealthy inventor. They are also seen in the alternate reality 1939 plot line in the film Sky Captain and the World of Tomorrow, and have an iconic association with the steampunk subcultural movement in broader terms. In 1989, Japanese animator Miyazaki released Kiki's Delivery Service, which features a Zeppelin as a plot element.

For the group's self-titled debut album, Page suggested the group use a picture of the Hindenburg crashing in New Jersey in 1937, much to Countess Eva von Zeppelin's disgust. Von Zeppelin tried to sue the group for using her family name, but the case was eventually dismissed. Modern era Since the 1990s Zeppelin Luftschifftechnik, a daughter enterprise of the Zeppelin conglomerate that built the original German Zeppelins, has been developing Zeppelin "New Technology" (NT) airships. These vessels are semi-rigids based partly on internal pressure, partly on a frame. The Airship Ventures company operated zeppelin passenger travel to California from October 2008 to November 2012 with one of these Zeppelin NT airships. In May 2011, Goodyear announced that they would replace their
