“The S-II stage was a nightmare the minute it was conceived, and it only got worse from there. During the course of its creation, it would grind up people and careers the way the transcontinental railway devoured laborers. Though the methods and materials used to build the S-II were reasonably well known, nobody had ever tried to apply them on such a titanic scale. Originally, it was to be somewhere around 8 stores tall with a diameter of 22 feet, but the width ballooned from there to 27 feet before the contract was even signed, then to 30, and finally to 33 feet. And all the while as the size of thing increased, NASA was trimming the allowable weight.” Harrison Storms of NAA.
After viewing the Apollo spaceport being built in Florida, President Kennedy flew on to Huntsville, Alabama. There, during a tour of Marshall and a briefing on the Saturn V and the lunar-rendezvous mission by von Braun, Jerome Wiesner interrupted Von Braun in front of reporters, saying, “No, that’s no good.” Webb immediately defended von Braun and lunar-orbit rendezvous. The adversaries engaged in a heated exchange until the President stopped them, stating that the matter was still subject to final review.
“I would like to reiterate once more that it is absolutely mandatory that we arrive at a definite mode decision within the next few weeks. . . . If we do not make a clear-cut decision on the mode very soon, our chances of accomplishing the first lunar expedition in this decade will fade away rapidly.” Wernher Von Braun June 7, 1962.
