"You look for a chap who has good eyesight, who has fast reactions, who has a good sense of balance, but most important, you look for someone who really loves to fly. It would be very difficult to make a good pilot out of a chap who hated it. We always incline to do best those things that we enjoy doing. Another thing you look for is a pilot who can learn his limitations. A poor pilot is not necessarily a dangerous pilot as long as he remains within his limitations. And you find your limits in the air, by getting closer and closer and closer and sometimes going beyond them and still getting out of it. If you go beyond and don’t get out of it, you haven’t learned your limitations, because you are dead."
