Question: Which astronaut flew on the Apollo 7 becoming NASA's 3rd civilian astronaut after Neil Armstrong and Elliot See?

<P0-S0> NASA's Astronaut Group 2, also known as The New Nine, was the second group of astronauts selected by NASA and announced on September 17, 1962. <P0-S1>  The group was required to augment the original Mercury 7 with the announcement of the Gemini program and leading to the Apollo program. <P0-S2>  While the Original 7 had been selected to accomplish the simpler task of orbital flight, the new challenges of rendezvous and lunar landing led to the selection of candidates with advanced engineering degrees (for four of the New Nine) as well as test pilot experience. <P0-S3>  Two of this group had been candidates for the original 7, but were not selected then for medical reasons. <P0-S4>  In addition, Group 2 became the first group with civilian test pilots in the group; See flew for General Electric, while Armstrong flew the X-15 research plane for NASA. <SEP> <P1-S0> Elliot McKay See Jr. (July 23, 1927 February 28, 1966) was an American engineer, naval aviator, test pilot, and NASA astronaut, selected in the second group of astronauts. <P1-S1>  Chosen as the prime command pilot for what would have been his first space flight, Gemini 9, he was killed with his crewmate Charles Bassett in a 1966 NASA trainer jet crash at the St. Louis, Missouri McDonnell Aircraft plant, where they were to take two weeks of space rendezvous simulator training. <SEP> <P2-S0> Ronnie Walter Cunningham (born March 16, 1932), (Col, USMCR, Ret.) <P2-S1> , better known as Walter Cunningham, is a retired American astronaut. <P2-S2>  In 1968, he was a Lunar Module Pilot on the Apollo 7 mission. <P2-S3>  He was NASA's third civilian astronaut (after Neil Armstrong and Elliot See), and has also been a fighter pilot, physicist, entrepreneur, venture capitalist, author of "The All-American Boys", lecturer, and host of the radio show "Lift-off to Logic". <P2-S4>  Walter Cunningham attended UCLA. <SEP> <P3-S0> Walter Marty "Wally" Schirra Jr. (March 12, 1923 – May 3, 2007), (CAPT, USN), was an American naval officer and aviator, aeronautical engineer, test pilot, and one of the original seven astronauts chosen for Project Mercury, United States first effort to put humans in space. <P3-S1>  He flew the six-orbit, nine-hour Mercury-Atlas 8 mission on October 3, 1962, becoming the fifth American, and the ninth human, to ride a rocket into space. <P3-S2>  In the two-man Gemini program, he achieved the first space rendezvous, station-keeping his Gemini 6A spacecraft within 1 ft of the sister Gemini 7 spacecraft in December 1965. <P3-S3>  In October 1968, he commanded Apollo 7, an 11-day low Earth orbit shakedown test of the three-man Apollo Command/Service Module. <P3-S4>  He was the first person to go into space three times, and the only person to have flown in Mercury, Gemini, and Apollo, logging a total of 295 hours and 15 minutes in space. <P3-S5>  He retired from the U.S. Navy at the rank of Captain and from NASA after his Apollo flight, becoming a consultant to CBS News for its coverage of the subsequent Apollo flights. <P3-S6>  He joined Walter Cronkite as co-anchor for the seven Moon landing missions.
