NASA announcement of The Selection of The Second Group

The selections were kept secret until three days later, although newspaper reports had circulated since earlier that year that he would be selected as the "first civilian astronaut".Armstrong was one of two civilian pilots selected for this group; the other was Elliot See, another former naval aviator. NASA announced the selection of the second group at a press conference on September 17, 1962. Compared with the Mercury Seven astronauts, they were younger, and had more impressive academic credentials.
