Robur the Conqueror

The story begins with strange lights and sounds, including blaring trumpet music, reported in the skies all over the world. The events are capped by the mysterious appearance of black flags with gold suns atop tall historic landmarks such as the Statue of Liberty in New York, the Great Pyramid of Giza in Egypt, and the Eiffel Tower in Paris. These events are all the work of the mysterious Robur,, a brilliant inventor who intrudes on a meeting of a flight-enthusiast's club called the Weldon Institute in Philadelphia, Pennsylvania. Members of the Weldon Institute are all firm believers that mankind shall master the skies using "lighter than air" craft, and that "heavier than air" craft such as airplanes and helicopters would be unfeasible. The institute has been constructing a giant dirigible called the Go-ahead, and are having a heated discussion of where to place its propeller (in front to pull it, or behind to push it) when Robur appears at the meeting and is admitted to speak to them. He chastises the group for being balloon-boosters when "heavier than air" flying apparatuses are the future. When asked if Robur himself has "made conquest of the air," he states that he has, leading to him accepting the title "Robur the Conqueror."
