The Adventures of Jo, Zette and Jocko

The Adventures of Jo, Zette and Jocko is a Franco-Belgian comics series created by Herge, the writer-artist best known for The Adventures of Tintin.

Jo, Zette and Jocko appear on the rear covers of some The Adventures of Tintin comic books, but never appear in the stories. A few Jo, Zette and Jocko comics allude to characters or events in The Adventures of Tintin.

Killed while exercising his love for speed in a racing car, millionaire John Archibald Pump leaves behind ten million US dollars. It will go to the builders of the first aeroplane to fly from Paris to New York at 1000 kilometres per hour. Jo and Zette's father sets about designing such a plane, but the project comes under threat from a gang of saboteurs led by William and Fred Stockrise, Pump's passed-over nephews who will only inherit if the ship is not completed within the year after the reading of the will, who go to all lengths, from theft to bombing, to prevent it.

The problem is there is a group of scoundrels led by Prime Minister Ramauni and the evil fakir Rabindah who aren't too keen on the idea.
