When the "Mayflower" crossed the ocean in 1620, the Atlantic was about sixty-seven days wide. Today it is about six hours wide by jet airliner. The ocean itself is the same; so is the yardstick of hours and days. What makes the difference?
At first glance one might say, "The paraphernalia of the jet age." But what makes all this paraphernalia possible?
Thought makes it possible. Step by step men have solved the problems of air transport by means of analysis, reason, insight, discovery. A jet airliner had to be conceived mentally before it could be built. So did the complex organization of airfields, flight control patterns, and communications systems supporting the flight. Every detail had to be thought out.
