On October 11, 1968, the Apollo 7 crew left the Earth atop a Saturn IB. They launched from launch complex 34, the pad on which the Apollo 1 crew had perished in a pre-launch fire the previous January, also atop a Saturn IB. The mission was an Earth orbital shakedown cruise of the Apollo Block II command and service modules, the one designed to support the lunar landing missions. The lunar module, still unfinished by that point, was absent. The Saturn IB couldn’t have launched the full stack into orbit anyways.
