Jack Swigert

John Leonard Swigert Jr. (August 30, 1931 – December 27, 1982) was an American NASA astronaut, test pilot, mechanical engineer, aerospace engineer, United States Air Force pilot, and politician. In April 1970, as command module pilot of Apollo 13, he became one of 24 astronauts who flew to the Moon.
Ironically, due to the "slingshot" route around the Moon they chose to safely return to Earth, the Apollo 13 astronauts flew further away from Earth than any other astronauts before or since, though they had to abort the Moon landing.

Before joining NASA in 1966, Swigert was a civilian test pilot and fighter pilot in the Air National Guard. After leaving NASA, he ran for Senate but lost in a primary election against Bill Armstrong. Later he ran for Congress, but while running was diagnosed with cancer. He won the election for Colorado's new 6th district in 1982, but died before being sworn in.
