Colonel (USAF) Ellison Shoji Onizuka
Astronaut/National Aeronautics and Space Administration, June 24, 1946 — January 28, 1986.

Colonel Onizuka was the first Japanese American astronaut selected to participate in America's Space Program.
Born and raised in a simple rural community, he walked a remarkable path that led from the coffee fields of Kona, Hawaii to miles above the earth. In 1985, he flew on a Departmet of Defense mission aboard the Space Shuttle Discovery, America's first classified manned military space flight. The Challenger flight was his second mission into space.
A humble man, he was especially proud of his Japanese heritage and remained genuinely grateful to all those responsible for his achievements.
The embarassed hero who was adored by children across many lands, he dreamed, he dared, and he delivered... "Your visions are not limited by what your eyes can see, but by what your minds can imagine. Make your life count and the world will be a better place because you tried." - Ellison S. Onizuka.
