It’s the 1920s. Aviation is in its infancy, yet all countries in Europe and around the world have already grasped the strategic importance of this revolutionary means of transportation. It opens endless opportunities simply by making the world a smaller place. Inventors and pioneers are testing the limits of existing technologies in a bid to push exploration and commerce as far as they can go. Germany is a forerunner of this push and its civil aviation goes as far as establishing a regular service linking Berlin to cities such as Moscow, Beijing and Shanghai.
