    don't forget about Apollo 4, an unmanned launch and very important for the
    program...

    Apollo 4 notes:
    
    http://science.ksc.nasa.gov/history/apollo/apollo-4/apollo-4.html
    
    During third orbit and after SPS engine burn, spacecraft coasted to a simulated
             translunar trajectory, reaching an altitude of 18,079 kilometers. The
    AS-501
             launch marked the initial flight testing of the S-IC and S-II stages.
    The first
             stage S-IC performed accurately with the center F-1 engine cutting off
    at 135.5
             seconds and the outboard engines cutting off at LOX depletion at 150.8
             seconds when the vehicle was traveling at 9660km/h at an altitude of
    61.6km.
             Stage seperation occured only 1.2 seconds off the predicted time.
    Cutoff of the
             S-II occured at 519.8 seconds.
