Few industries capture our imagination or move the global economy quite like aviation. In any given moment, thousands of aircraft are aloft, carrying travelers and cargo across continents in a matter of hours instead of the weeks that alternatives take.

Behind the romance of flight sits a vast machine of pilots, technicians, airports, and airlines. Here are some of the most fascinating facts about aviation from across the industry.
