Who was John "Jack" Swigert, Jr.?

John "Jack" Swigert, Jr. is best known as an astronaut and Congressman-elect. He gained fame as a member of the Apollo 13 crew, which faced a life-threatening crisis in space when an oxygen tank exploded. Swigert's critical role during the mission highlighted his skills as a pilot and problem solver under extreme pressure.

Following his work as an astronaut, Swigert was elected to the United States House of Representatives for Colorado but sadly passed away from cancer before he could take office. His contributions to space exploration and his brief political career make him a significant figure in both fields.

The other options, while notable in their own right, do not accurately describe Swigert. He did not serve as a senator, nor was he known as an explorer or a civil rights leader. His legacy primarily stems from his accomplishments in aerospace and his brief political path.
