Publisher's Synopsis
En route to Sydney, Australia, Tintin, Milyn, Capten Hadoc, and the nutty scientist Ephraim R. Efflwfia accept an invitation from the tight-fisted Laszlo Carreidas, the millionaire who never laughs, to fly in his private jet. During the flight, the plane is hijacked, but Tintin and his friends find a hiding place. A Welsh adaptation of Flight 714 to Sydney.
