Question: Jean-Jacques Favier and Klaus-Dietrich Flade, both flew in space as which occupation ?

full_context: Document 1: Soyuz TM-29: Soyuz TM-29 was a Russian manned spacecraft launched from the Baikonur Cosmodrome aboard a Soyuz 11A511U rocket. It docked with Mir on February 22 at 05:36 GMT with Cosmonauts Viktor Afanasyev of Russia, Jean-Pierre Haigneré of France, and Ivan Bella of Slovakia aboard. Since two crew seats had been sold (to Slovakia and France), Afanasyev was the only Russian cosmonaut aboard. This meant that Russian engineer Avdeyev already aboard Mir would have to accept a double-length assignment. After the February 27 departure of EO-26 crew commander Padalka and cosmonaut Bella aboard Soyuz TM-28, the new EO-27 Mir crew consisted of Afanasyev as Commander, Avdeyev as Engineer and French cosmonaut Haigneré.
Document 2: Jean-Pierre Haigneré: Jean-Pierre Haigneré (born 19 May 1948) is a French Air Force officer and a former CNES spationaut.
Document 3: Jean-François Clervoy: Jean-François André Clervoy (born 19 November 1958) is a French engineer and a CNES and ESA astronaut. He is a veteran of three NASA Space Shuttle missions.
Document 4: Christer Fuglesang: Arne Christer Fuglesang (] ) (born March 18, 1957 in Stockholm) is a Swedish physicist and an ESA astronaut. He was first launched aboard the STS-116 Space Shuttle mission on December 10, 2006, at 01:47 GMT, making him the first Swedish citizen in space.
Document 5: Soyuz TM-3: Soyuz TM-3 was the third manned spacecraft to visit the Soviet space station Mir, following Soyuz-T15 and Soyuz-TM2. It was launched in July 1987, during the long duration expedition Mir EO-2, and acted as a lifeboat for the second segment of that expedition. There were three people aboard the spacecraft at launch, including the two man crew of the week-long mission Mir EP-1, consisting of Soviet cosmonaut Alexander Viktorenko and Syrian Muhammed Faris. Faris was the first Syrian to travel to space, and as of November 2010, the only one. The third cosmonaut launched was Aleksandr Aleksandrov, who would replace one of the long duration crew members Aleksandr Laveykin of Mir EO-2. Laveykin had been diagnosed by ground-based doctors to have minor heart problems, so he returned to Earth with the EP-1 crew in Soyuz TM-2.
Document 6: Jay Greene: Jay H. Greene is a retired NASA engineer. Between 2000 and 2004, he served as Chief Engineer at Johnson Space Center, where his role consisted primarily of advising the Center Director. He worked as a FIDO flight controller during the Apollo Program and a flight director from 1982 to 1986, most notably as ascent flight director during the Challenger accident in 1986. Greene worked for four years as a manager on the International Space Station project and received several awards for his work including the NASA Distinguished Service Medal. After his retirement in 2004 he served as a part-time consultant on the Exploration Systems Architecture Study. NASA Associate Administrator Rex Geveden described him as "a famous technical curmudgeon in the Agency."
Document 7: Sigmund Jähn: Sigmund Werner Paul Jähn (born 13 February 1937) is a German cosmonaut and pilot, who in 1978 became the first East German (and German native) to fly in space as part of the Soviet Union's Interkosmos programme.
Document 8: Klaus-Dietrich Flade: Klaus-Dietrich Flade (born August 23, 1952) is a German pilot and former German Aerospace Center astronaut who visited the Mir space station in 1992 aboard the Soyuz TM-14 mission, returning to Earth a week later aboard Soyuz TM-13.
Document 9: Franz Viehböck: Franz Artur Viehböck (born August 24, 1960 in Vienna) is an Austrian electrical engineer, and was Austria's first cosmonaut. He was titulated "„Austronaut“" by his country's media. He visited the Mir space station in 1991 aboard Soyuz TM-13, returning aboard Soyuz TM-12 after spending just over a week in space.
Document 10: Jean-Jacques Favier: Jean-Jacques Favier (Born April 13, 1949) is a French engineer and a former CNES astronaut who flew aboard the STS-78 NASA Space Shuttle mission. Favier was due to fly aboard the Columbia mission in 2003, but later signed out of the mission.
Document 11: Ulf Merbold: Dr. Ulf Dietrich Merbold (born June 20, 1941) is the first West German citizen and second German native (after Sigmund Jähn) to have flown in space. He is also the first member of the European Space Agency Astronaut Corps to participate in a spaceflight mission and the first non-US citizen to reach orbit in a US spacecraft. In 1983, he and Byron Lichtenberg became the first Payload Specialists to fly on the shuttle.
Document 12: Soyuz TMA-17M: Soyuz TMA-17M was a 2015 flight to the International Space Station. It transported three members of the Expedition 44 crew to the International Space Station. TMA-17M was the 126th flight of a Soyuz spacecraft; the first having occurred in 1967. The crew consisted of a Russian commander accompanied by Japanese and American astronauts. The capsule remained docked to the space station for about five months until the scheduled departure of Expedition 45 in December 2015. Soyuz TMA-17M landed safely on the steppes of Kazakhstan on 11 December, 2015, in a rare night landing.
Document 13: 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.
Document 14: Martin J. Fettman: Martin Joseph Fettman (B.S., D.V.M., M.S., Ph.D., Diplomate, ACVP) is an American pathologist and researcher who flew on NASA Space Shuttle mission STS-58 aboard the Space Shuttle Columbia as a Payload Specialist.
Document 15: Jack D. Fischer: Jack David Fischer (born January 23, 1974) is an American engineer, test pilot and a NASA astronaut. Fischer was selected in June 2009 as a member of the NASA Astronaut Group 20 and qualified as an astronaut in 2011. He made his first spaceflight in April 2017, as a flight engineer for Expedition 51/52 on the International Space Station.
