The essence of life, I concluded, did not lie in the material. It penetrated, but was not bound to, the physical world of science.

These phantoms speak with human voices — friendly, vapor- like shapes, without substance, able to vanish or appear at will, to pass in and out through the walls of the fuselage as though no walls were there.

I may be flying a complicated airplane, rushing through space, but in this cabin I'm surrounded by simplicity and thoughts set free of time. How detached the intimate things around me seem from the great world down below. How strange is this combination of proximity and separation. That ground - seconds away - thousands of miles away. This air, stirring mildly around me. That air, rushing by with the speed of a tornado, an inch beyond. These minute details in my cockpit. The grandeur of the world outside. The nearness of death. The longness of life.
