Jack Swigert was one of the 19 astronauts selected by NASA in April 1966. He served as a member of the astronaut support crew for the Apollo 7 mission.  He was next assigned to the Apollo 13 backup crew and subsequently called upon to replace prime crewman Ken Mattingly as Command Module Pilot.  In November 1982 he was elected to the U.S. House of Representatives. He sadly died on December 28, 1982 of bone cancer, before he could be sworn in.
