Apollo 1
Apollo 1

On January 27, 1967, a preflight test for the Apollo One mission went poorly and a huge fire covered the launch pad.  Astronauts Virgil Grissom, Edward White and Roger Chaffee lost their lives when the fire swept through the command module. This mission was to be the first crewed flight in the Apollo missions and was scheduled to launch on Feb. 21, 1967. In the spring of 1967, NASA's Associate Administrator for Manned Space Flight, Dr. George E. Mueller, announced that the mission originally scheduled for Grissom, White and Chaffee who ended up dying in the fire would be known as Apollo 1, and said that the first Saturn V rocket launch, scheduled for November 1967, would be known as Apollo 4. No missions were ever given the title of Apollo Two or Three for some reason.
