Question: The movie Apollo 13 featured an astronaut that was born in what year?
Context: Astronaut Group 6 (the 'XS-11') was announced by NASA on August 11, 1967, the second group of scientist-astronauts.  Only five of the eleven were given formal assignments in the Apollo program and these were all non-flying support crew positions.  (Chapman was a support crew member on Apollo 14 and Apollo 16; Parker was assigned to Apollo 15 and Apollo 17; England was assigned to Apollo 13 and Apollo 16; and Henize and Allen rounded out the Apollo 15 support crew.) Stainless steel commemorative plaques measuring 9 by were attached to the ladders on the descent stages of the United States Apollo Lunar Modules flown on lunar landing missions Apollo 11 through Apollo 17, to be left permanently on the lunar surface.  The plaques were originally suggested and designed by NASA's head of technical services Jack Kinzler, who oversaw their production.  All of the plaques bear facsimiles of the participating astronauts' signatures.  For this reason, an extra plaque had to be made for Apollo 13 due to the late replacement of one crewmember.  The first (Apollo 11) and last (Apollo 17) plaques bear a facsimile of the signature of Richard Nixon, President of the United States during the landings, along with references to the start and "completion" of "man's" "first" explorations of the Moon and expressions of peace for "all mankind".  All, except the Apollo 12 plaque (which is also textured differently), bear pictures of the two hemispheres of Earth.  Apollo 17's plaque bears a depiction of the lunar globe in addition to the Earth.  The plaques used on missions 13 through 16 bear the call-sign of each mission's Lunar Module.  All the plaques were left on the Moon, except the two for the aborted Apollo 13 which did not land on the Moon. Leon Theodore "Lee" Silver, Ph. D (born April 9, 1925), Professor of Geology at California Institute of Technology (Caltech), was an instructor to the Apollo 13, 15, 16, and 17 astronaut crews.  Working with the National Aeronautics and Space Administration (NASA), he taught astronauts how to perform field geology, essentially creating lunar field geology as a new discipline.  His training is credited with a significant improvement in the J-Mission Apollo flights' scientific returns.  After the Apollo program, he became a member of the United States National Academy of Sciences in 1974.  Currently, he is the W. M. Keck Foundation Professor for Resource Geology, emeritus, at Caltech. Milton "Milt" Windler is a retired NASA Flight Director.  He is best known for his work as one of the four flight directors of Apollo 13 Mission Operations Team, all of whom were awarded the Presidential Medal of Freedom by President Richard M. Nixon for their work in guiding the crippled spacecraft safely back to Earth.  Previously a jet fighter pilot, he began working at NASA in 1959 during Project Mercury.  Originally working in the recovery division, he was promoted to flight director by Chris Kraft to support Eugene Kranz, who had acquired additional responsibilities in the months following the Apollo 1 fire.  Windler also served as flight director for Apollo 8, Apollo 10, Apollo 14, Apollo 15, and all three Skylab missions.  Following the conclusion of the Apollo Program, Windler worked in the Space Shuttle Project Office on Remote Manipulator Systems Operations until 1978.  He is a recipient of the NASA Exceptional Service Medal. John Leonard "Jack" Swigert Jr. (August 30, 1931 – December 27, 1982) was an American test pilot, mechanical and aerospace engineer, United States Air Force pilot, and NASA astronaut, one of the 24 people who have flown to the Moon. "Houston, we have a problem" is a popular but erroneous quote from the radio communications between the Apollo 13 astronaut Jack Swigert and the NASA Mission Control Center ("Houston") during the Apollo 13 spaceflight, as the astronauts communicated their discovery of the explosion that crippled their spacecraft.  The erroneous wording was popularized by the 1995 film "Apollo 13", a dramatization of the Apollo 13 mission, in which actor Tom Hanks, portraying Mission Commander Jim Lovell, uses that wording, which became one of the film's taglines. Thomas Kenneth Mattingly II (born March 17, 1936), (RADM, USN, Ret.) , better known as Ken Mattingly, is a former American naval officer and aviator, aeronautical engineer, test pilot, Rear Admiral in the United States Navy and astronaut who flew on the Apollo 16, STS-4 and STS-51-C missions.  He had been scheduled to fly on Apollo 13, but was held back due to concerns about a potential illness (which he did not contract).  He later flew as Command Module Pilot for Apollo 16, making him one of only 24 people to have flown to the Moon. Lost Moon: The Perilous Voyage of Apollo 13 (published in paperback as Apollo 13), is a non-fiction book first published in 1994 by astronaut James Lovell and journalist Jeffrey Kluger, about the failed April 1970 Apollo 13 lunar landing mission which Lovell commanded.  The book is the basis of the 1995 film adaptation "Apollo 13", directed by Ron Howard. Apollo 13 is a 1995 American space adventure docudrama film directed by Ron Howard and starring Tom Hanks, Kevin Bacon, Bill Paxton, Gary Sinise, and Ed Harris.  The screenplay by William Broyles, Jr. and Al Reinert, that dramatizes the aborted 1970 Apollo 13 lunar mission, is an adaptation of the book "Lost Moon: The Perilous Voyage of Apollo 13" by astronaut Jim Lovell and Jeffrey Kluger.  The film depicts astronauts Lovell, Jack Swigert, and Fred Haise aboard Apollo 13 for America's third Moon landing mission.  En route, an on-board explosion deprives their spacecraft of most of its oxygen supply and electric power, forcing NASA's flight controllers to abort the Moon landing, and turning the mission into a struggle to get the three men home safely. Fred Wallace Haise Jr. ( ; born November 14, 1933) is an American former NASA astronaut, fighter pilot with the U.S. Marine Corps and the U.S. Air Force and test pilot.  He is one of only 24 people to have flown to the Moon, having flown as Lunar Module Pilot on Apollo 13.  He was to have been the sixth person to land and walk on the Moon, but the Apollo 13 mission was aborted before lunar landing.  He went on to fly Space Shuttle Approach and Landing Tests in 1977, and retired from NASA in 1979.
