" When he climbed into the Penelope or any other airplane, the same change always came over him and the character of the change was so strong that even Stutz himself was aware of it. He exchanged his earthly freedom of thinking for what had to be a series of disciplined facts. To absorb and segregate these facts, all in their right and proper order, was his duty, a$ it was of any professional pilot. Not only was it his duty but it was his sole defense against dependency on luck, and although he was aware of the power of luck, it was indicative that Stutz never considered it as a means to an end as long as he was flying.
