The man who was almost NASA's first Black astronaut in the 1960s explains why he never made it to space

• "The Space Race" is a new documentary about some of the first Black astronauts.
• NASA trained Ed Dwight and Robert Lawrence to become astronauts in the 1960s.
• But NASA didn't send an African-American astronaut to space until 1983.

On August 30, 1983, NASA sent Guion Bluford, the first African-American astronaut, to space. 

Two decades before Bluford's flight, Ed Dwight was an Air Force pilot who trained to be the first Black astronaut. A new documentary explores why he never made it into orbit.
