The second group potentially includes most pilots, including, I believe, John and me in the ’70s. We all became pilots because we were willing to take on a very tough challenge over an extended period of time. We studied a body of knowledge and then submitted to a test on it. We learned difficult skills that we weren’t certain, in the beginning, we could master. Nearly every learning pilot says at one time or another, “You know, I’m not sure I’m going to be able to do this.” Then we soloed and took our lives into our own hands thousands of feet above the ground. We persisted, presented ourselves for evaluation and became certificated pilots.
