National Aviation Day is August 19. It seems only right to celebrate the marvel that is aviation. We are living in a world where you can fly from one side of the country to the other in a matter of hours, take romantic hot-air balloon rides, have family fun on windy days flying kites, watch real-time space flights never before thought of, and have a drone deliver packages to your door. But to understand how we got to this point, we need to look into the past.
