I want to be remembered for only one thing: my contribution to aviation.

Play off everyone against each other so that you have more avenues of action open to you.

My father told me, never have partners.

I put the sweat of my life into this project, and if it's a failure, I'll leave the country and never come back.

Sometimes I truly fear that I am losing my mind. And if I did it it would be like flying blind.

Wash four distinct and separate times, using lots of lather each time from individual bars of soap.

I am by nature a perfectionist, and I seem to have trouble allowing anything to go through in a half-perfect condition. So if I made any mistake it was in working too hard and in doing too much of it with my own hands.
