Aircraft such as this Dornier Do X (Germany) represent the desire of the world powers in the 1930s to showcase their political, economic, and technological prowess with transoceanic airline service. Much like the capability to launch satellites today, successful demonstrations of overseas airline service provided nations with considerable domestic and international prestige.
The monster Do X was too complex and expensive to operate regular overseas commercial service.
