Astronauts Virgil I. “Gus” Grissom, Edward H. White II and Roger B. Chaffee were killed when a fire erupted in their capsule during testing on the launch pad on Jan. 27, 1967. The mission, originally known as SA-204, was later designated as Apollo 1.
Grissom, 40, the mission commander, was preparing for his third trip to space. White, 36, made history in 1965 as America’s first spacewalker. Chaffee, 31, was a Navy pilot and NASA rookie looking forward to his first space flight.
