On August 9, Gilruth, Low, Kraft and Slayton flew to Marshall Space Flight Center in Huntsville, Alabama, where they briefed NASA managers including Wernher von Braun and Rocco Petrone on the planned mission. On August 14, they, along with the Huntsville group, traveled to NASA Headquarters in Washington, D.C. to brief Deputy Administrator Thomas O. Paine. In turn, Paine recommended the mission to Administrator James E. Webb, who gave Kraft and his colleagues the authority to begin preparations for the mission.[1]
