On January 27, 1967, tragedy struck the space race, as the AS-204 mission (better known by its later name of Apollo 1) suffered a malfunction during a training exercise on the launch pad, causing a fire that ultimately killed all three crew members onboard. The deaths of Virgil Grissom, Edward White and Roger Chaffee prompted NASA to completely redesign its command modules, delaying any further missions. Nearly 21 months later, Apollo 7 became the next manned mission to completed and launched.
