History has shown that the key to progress, as well as survival, has been the ability to transport people and items of commerce. From the earliest references in literature, advancements in modes of travel were chronicled and embraced by the masses. This included the domestication of draft animals with the use of the wheel, to improvements in shipping, railways and, more recently, air travel. All of these improvements allowed the economical movement of growing quantities of goods over greater distances, along with the critically important ability to provide modern society with an individualized and reliable means of personal transportation.
For all of these modes of transportation the key to their continuing success was, and continues to be, their ability to innovate, improve their efficiency and effectively become more economical. In all cases, it is (1) the initial breakthrough idea; followed by (2) continuous improvements in the technology; (3) implementation and improvements in the infrastructure that supported the use of the technology; and (4) the societal changes that occurred that are all a part of the natural order of things.
With these changes and improvements, the older less reliable and efficient modes of transportation were set aside or relegated to curiosities or featured in parades and exhibitions. Each older technology had its day and served to advance the, then, current societal and personal transportation needs. What came next was in most cases a breakthrough technology, often referred to as a game changer, which advanced the ability to move individuals faster, farther and more economically. It also allowed the movement of greater volumes of goods over greater distances, again, more economically and reliably.
