The idea of racial inferiority or superiority is foreign to me. I can't feel inferior or superior to another man because of race, or in any way antagonistic to him.

In wilderness I sense the miracle of life, and behind it our scientific accomplishments fade to trivia.

How long can men thrive between walls of brick, walking on asphalt pavements, breathing the fumes of coal and of oil, growing, working, dying, with hardly a thought of wind, and sky, and fields of grain, seeing only machine-made beauty, the mineral-like quality of life?

It is about a period in aviation which is now gone, but which was probably more interesting than any the future will bring. As time passes, the perfection of machinery tends to insulate man from contact with the elements in which he lives.

Like a train tunneling through a mountain, they will be aloof from both the problems and the beauty of the earth's surface.
