Seated in Mission Control, Chris Kraft neared the end of a tedious Friday afternoon as he monitored a seemingly interminable ground test of the Apollo 1 spacecraft. It was January 1967, and communications between frustrated astronauts inside the capsule on its Florida launch pad and the test conductors in Houston sputtered periodically through his headset. His mind drifted.
Sudden shouts snapped him to attention. In frantic calls coming from the Apollo cockpit, fear had replaced frustration. Amid the cacophony, Kraft heard the Apollo program’s most capable astronaut, Gus Grissom, exclaim a single word.
