Astronaut Duke - Landed with sixty seconds of fuel remaining

General Charles M. Duke was a former astronaut who went on the Apollo 16 mission to the moon. I asked, “Once you were there, weren’t you free to make your own decisions and carry out your own experiments?” He smiled and said “Sure, if I didn’t want to return to earth!” He went on to describe the intricate plan, the precise instructions, the essential discipline, and the instant obedience that was needed right down to the second. He explained how they landed with sixty seconds of fuel remaining. Talk about obedience! (Charles Swindoll, Strengthening Your Grip).
