I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth.

To exclude from positions of trust and command all those below the age of 44 would have kept Jefferson from writing the Declaration of Independence, Washington from commanding the Continental Army, Madison from fathering the Constitution, Hamilton from serving as secretary of the treasury, Clay from being elected speaker of the House and Christopher Columbus from discovering America.
