                 <p>Never in all their history have men been able truly to conceive of the world as one: a single sphere, a globe, having the qualities of a globe, a round earth in which all the directions eventually meet, in which there is no center because every point, or none, is center — an equal earth which all men occupy as equals. The airman\'s earth, if free men make it, will be truly round: a globe in practice, not in theory.</p>
                 <p>Science cuts two ways, of course; its products can be used for both good and evil. But there\'s no turning back from science. The early warnings about technological dangers also come from science.</p>

                 <p>Spaceflights cannot be stopped. This is not the work of any one man or even a group of men. It is a historical process which mankind is carrying out in accordance with the natural laws of human development.</p>

                 <p>Space, the final frontier. These are the voyages of the Starship Enterprise. Its five-year mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before.</p>
                 <p>As I stand out here in the wonders of the unknown at Hadley, I sort of realize there’s a fundamental truth to our nature, Man must explore, and this is exploration at its greatest.</p>
