Which was an air force officer and an ESA astronaut, Claude Nicollier or Roberto Vittori?
Claude Nicollier Claude Nicollier (born 2 September 1944 in Vevey, Switzerland) is the first astronaut from Switzerland. He has flown on four Space Shuttle missions. His first spaceflight (STS-46) was in 1992, and his final spaceflight (STS-103) was in 1999. He took part in two servicing missions to the Hubble Space Telescope (called STS-61 and STS-103). During his final spaceflight he participated in a spacewalk, becoming the first European Space Agency astronaut to do so during a Space Shuttle mission (previous ESA astronauts conducted spacewalks aboard "Mir", see List of spacewalks and moonwalks 1965–1999). In 2000 he was assigned to the Astronaut Office Extravehicular Activity Branch, while maintaining a position as Lead ESA Astronaut in Houston. Nicollier retired from ESA in April 2007.
Frank Borman Frank Frederick Borman II (born March 14, 1928), (Col, USAF, Ret.), is a retired United States Air Force pilot, aeronautical engineer, test pilot, and NASA astronaut, best remembered as the Commander of Apollo 8, the first mission to fly around the Moon, making him, along with crew mates Jim Lovell and Bill Anders, the first of only 24 humans to do so. Before flying on Apollo, he set a fourteen-day spaceflight endurance record on Gemini 7, and also served on the NASA review board which investigated the Apollo 1 fire. After leaving NASA, he was the Chief Executive Officer (CEO) of Eastern Air Lines from 1975 to 1986. Borman is a recipient of the Congressional Space Medal of Honor.
