'John Glenn the Humanitarian' Remembered by NASA Chief (Video)

John Glenn was an outstanding aviator, astronaut and ambassador for the American space program, but he was an even better human being, NASA Administrator Charlie Bolden said. John Glenn the humanitarian, John Glenn the human being, John Glenn the husband, you know, the loving husband — that's what I'll remember forever," Bolden said in a NASA video tribute, choking back tears. The NASA chief is one of many in the spaceflight community and beyond now mourning Glenn, who died yesterday (Dec. 8) at the age of 95.
