Siege of Fort Bismarck
For the filming, in addition to the elaborate miniature of the Farman MF.11 and Etrich Taube with a wingspan of 1 meter or more, a full-scale model for shooting the main story with a propeller rotating was produced. In both cases, the shooting was done in addition to the set, and on Mt. Fuji, it was filmed from a helicopter. The full-scale model of the Farman MF.11 seaplane was assembled by a craftsman specializing in gliders by borrowing the disassembled actual machine saved by the Japan Aeronautic Association and creating a restoration drawing. The seaplane carrier Wakamiya was also photographed using a cargo ship.
