Question: Which pilot was born earlier, Klaus-Dietrich Flade or Philippe Perrin?

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: 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 4: 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 5: Philippe Perrin: Philippe Perrin (Colonel, French Air Force) (born January 6, 1963) is a French test pilot and former CNES and European Space Agency astronaut.

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 9: 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.

In 1985, he became the second French citizen in space, after Jean-Loup Chrétien, when he flew aboard NASA's Space Shuttle mission STS-51-G.
Document 11: 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 12: Ulrich Walter: Prof. Dr. Ulrich Hans Walter (born February 9, 1954) is a German physicist/engineer and a former DFVLR astronaut.
Document 13: Michael Collins (astronaut): Michael Collins (born October 31, 1930) (Major General, USAF, Ret.), is an American former astronaut and test pilot. Selected as part of the third group of fourteen astronauts in 1963, he flew into space twice. His first spaceflight was on Gemini 10, in which he and Command Pilot John Young performed two rendezvous with different spacecraft and Collins undertook two extra-vehicular activities (EVAs). His second spaceflight was as the Command Module Pilot for Apollo 11. While he stayed in orbit around the Moon, Neil Armstrong and Buzz Aldrin left in the Lunar Module to make the first manned landing on its surface. He is one of 24 people to have flown to the Moon.
Document 14: 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.
