Chuck Yeager’s Air Combat would ask for various airplane specs (“what is the service ceiling of an F-4E?,” “what is the ferry range of a MiG-15?”), and you had to flip through a booklet to find the answer.
You could copy the book, but it was fairly long so I guess the friction kept you in check.




I feel like logging in as root on a headless system and hoping you type the command(s) to restore functionality is a rite of passage.
