Mission Control will be perfect. When you leave this meeting today you will go to your office and the first thing you will do there is to write -Tough and Competent- on your blackboards. It will never be erased. Each day when you enter the room these words will remind you of the price paid by Grissom, White, and Chaffee. These words are the price of admission to the ranks of Mission Control.
