Description:When the Stratoship H-22, designed by their father, is the subject of an
attempted bombing from the air, Jo and Zette fly it out of its hangar but are unable to get back. Crash-landing near the North Pole
they face a race against time to get the plane back home and win the
trans-Atlantic challenge. But the Stockrise brothers and their gang are
still determined to thwart the operation even if Jo and Zette
successfully make it home.
