As the human population continues to grow exponentially, more and more people are taking to the skies and flying in airplanes. Furthermore, new airports are being built, old airports are being refurbished for additional space, and advanced airplane models are undergoing an extensive series of aerodynamical tests in order to fly the skies with a greater quantity of passengers per plane: It's only a matter of time before 1000 passengers are crammed like sausages into a single plane. On top of that, as the number of people taking to the skies increases, so does the number of people in the skies at any given moment. Now, currently only many thousands of passengers are in the skies worldwide at any given moment. However, will there come a point in time when there could be as many as 1 billion people in the skies aboard planes at any given moment? If so, how will air traffic control be able to manage such an overwhelming work load?
