Possibly everyone will travel by air in another fifty years. I'm not sure I like the idea of millions of planes flying around overhead. I love the sky's unbroken solitude. I don't like to think of it cluttered up by aircraft, as roads are cluttered up by cars. I feel like the western pioneer when he saw barbed-wire fence lines encroaching on his open plains. The success of his venture brought the end of the life he loved.

Success is not measured by what a man accomplishes, but by the opposition he has encountered and the courage with which he has maintained the struggle against overwhelming odds.

Now, all that I feared would happen has happened. We are at war all over the world, and we are unprepared for it from either a spiritual or a material standpoint.

God made life simple. It is man who complicates it.

Aviation seems almost a gift from heaven to those Western nations who were already the leaders of their era, strengthening their leadership, their confidence, their dominance over other peoples.

I realized that the future of aviation, to which I had devoted so much of my life, depended less on the perfection of aircraft than on preserving the epoch-evolved environment of life, and that this was true of all technological progress.

Science intensifies religious truth by cleansing it of ignorance and superstition.
