"We had taken up the invention of the flying machine as a sport."

"The problem was not to build a machine that would fly, but to build a machine that would fly safely."

"The desire to fly is an idea handed down to us by our ancestors who, in their weary journeys over endless plains, yearned for a swifter and less laborious mode of travel."

"The best thing about being a man of science is that you never have to be bored."

"The greatest pleasure in life is to do what people say you cannot do."
