"...The crew of the space shuttle Challenger honored us by the manner in which they lived their lives. We will never forget them nor the last time we saw them -- this morning -- as they prepared for their journey and waved goodbye, and slipped the surly bonds of Earth to touch the face of God." -- President Reagan Addresses the Nation, January 28, 1986
