Orville Wright

"In just six weeks from the time the design was started, we had the motor on the block testing its power."

"The course of the flight up and down was exceedingly erratic, partly due to the irregularity of the air, and partly to lack of experience in handling this machine. The control of the front rudder was difficult on account of its being balanced too near the center."

"If we all worked on the assumption that what is accepted as true is really true, there would be little hope of advance."

"With all the knowledge and skill acquired in thousands of flights in the last ten years, I would hardly think today of making my first flight on a strange machine in a twenty-seven mile wind, even if I knew that the machine had already been flown and was safe."
