On 27 January 1967, three astronauts died during a ground test of the Apollo 1 spacecraft. After the investigation, NASA substantially redesigned the spacecraft and its safety practices: among other changes, it installed a hatch that could be opened from inside or outside in three seconds and more strictly controlled combustible materials. Apollo 11 launched in July 1969, about two and a half years after the tragedy. NASA documents numerous changes, but its official materials do not substantiate the original item’s figure of “125.”
