The first chief of the astronaut office, Deke Slayton, had high praise for Young in his autobiography Deke! “John was one of the unsung heroes of the Astronaut Office, a real hardworking guy who did whatever you asked him to, no problems. The only thing that held him back was that he was not comfortable with public speaking; he tended to freeze up and give one-word answers.”
Amazing career, amazing achievements. Somehow, this paragraph resonated the most with me.
