In the century that’s elapsed since the dawn of commercial aviation, air transportation has become pretty well refined. Yet paradoxically, it’s easier to fly halfway around the world than to travel to a nearby city. As a result, many people shun air travel when taking short trips.

Consider the process: From an origin point, you must first travel via car or rail to an often-distant metropolitan hub airport. Then, you wait in line to pass through security. You wait some more to board at the gate. You and your fellow passengers wait still more to taxi to the runway before your plane finally takes off. Then you repeat most of the ordeal in reverse on the other end, having spent approximately 70 percent of your travel time on the ground. It’s little wonder that in the United States, 10 percent of round-trips between 800 and 1,600 kilometers (500 to 1,000 miles) and less than half a percent of those under 800 km are undertaken by air.
