We take for granted our ability to drive hundreds of miles in just a few hours time. We don’t think twice about being able to stand on two different continents in the same day. For thousands of years, we were limited to where we could walk. For hundreds of years, we were limited to where we could float. It’s only in the last 100 years, the blink of an eye, that the automobile and airplane have enabled us to span the globe. The evolution of travel will continue into the future, and we are nearing a new step in that process.
