Apollo 4 flew the S-IC first stage and S-II second stage for the first time, and demonstrated the first in-flight restart of the S-IVB third stage. The launch, at 7am EST on November 9, 1967 from Launch Complex 39, was the first from the John F. Kennedy Space Center on Merritt Island, Florida. The mission tested the complete Saturn V and Apollo Command/Service Module (CSM) stack in what is known in the aerospace industry as an "all-up test", meaning all stages were live and functional on the first flight. The mission used a Block I CSM modified to test several important Block II revisions, including its heat shield at simulated lunar-return speeds of approximately 36500 feet per second (11100 m/s). The mission was deemed a complete success by NASA, and significantly advanced Apollo toward its goal of landing men on the Moon by the end of the 1960s. This was the ...
