Please answer this: Generate a question that has the following answer: The explosion for the following movie plot: In a technologically advanced 1939, the zeppelin Hindenburg III arrives in New York City, mooring atop the Empire State Building. Aboard the airship is Dr. Jorge Vargas (Julian Curry), a scientist who arranges for a package containing two vials to be delivered to Dr. Walter Jennings (Trevor Baxter). Moments later, as the courier looks back while leaving with the vials, Dr. Vargas is nowhere to be seen. Polly Perkins (Gwyneth Paltrow), a newspaper reporter for The Chronicle, is looking into the disappearances of Vargas and five other renowned scientists. She receives a cryptic message telling her to go to Radio City Music Hall. Ignoring the warning of her editor, Mr. Paley (Michael Gambon), she meets Dr. Jennings during a showing of The Wizard of Oz. Dr Jennings tells Polly that Dr. Totenkopf ("Skull" in German) is coming for him next. Suddenly, air raid sirens go off as giant, seemingly indestructible robots attack the city. Clearly outmatched, the police and other authorities call for "Sky Captain" Joe Sullivan (Jude Law). Joe commands a private air force based in New York State known as the Flying Legion. Polly shows little regard for her personal safety as she photographs the action from the street. Meanwhile, Joe engages the robots with his highly modified Curtiss P-40 pursuit fighter and eventually manages to disable one robot. The rest of the robots leave soon after. News reports show similar attacks around the globe. The disabled robot is taken back to the Legion's air base so that its science and technology expert, Dex (Giovanni Ribisi), can examine it. Polly follows, hoping to get information for her story. She and Joe are ex-lovers who broke up three years earlier in China, where Joe was serving with the Flying Tigers. Since it appears Polly has useful information, Joe reluctantly agrees to let her in on the investigation. Her lead takes them to the ransacked laboratory of Dr. Jennings, with the scientist himself near death. The mysterious female assailant (Bai Ling) escapes. Just before he dies,...
