1968: NASA launches Apollo 7, the first successful manned Apollo mission, with astronauts Wally Schirra, Donn F. Eisele and Walter Cunningham aboard. Its 11-day Earth-orbital flight allowed the crew to check life-support, propulsion and control systems, clearing the way for the flight of Apollo 8 to orbit the Moon just two months later.
