At this moment, wherever you are sitting in the world, the sky above you is the equivalent of a large city. Collect all these cities and air spaces around the world and you have an eighth continent – not one of land or ice, but a magnificent and crowded atmosphere filled with people in airplanes. Thousands and thousands of airplanes all over the world are bringing people to this lofty continent, bigger than much of Europe, all of Australia or many Antarctica’s. Enveloping the globe with its unique ecosystem, it has the most diverse population group in the history of the planet. Leading minds must look up as well as forward. The fact is that we are leaving the earth, and this eighth continent is our jumping off point to the cosmos.
