Former President George H.W. Bush released the following statement following his death.

"Barbara and I join our fellow Americans and many friends in the space community in mourning the loss of astronaut John Young. John was more than a good friend; he was a fearless patriot whose courage and commitment to duty helped our Nation push back the horizon of discovery at a critical time. To us, he represented the best in the American spirit — always looking forward, always reaching higher. John leaves a tremendous legacy of accomplishment, in addition to his wonderful family. May his memory serve to inspire future generations of explorers to dare greatly, act boldly, and serve selflessly."
