NASA astronauts John Glenn (C), Alan Shepard (R) and Gus Grissom (L)

John Glenn, one of America’s heroes of the 20th Century, died last Thursday at age 95. Glenn was a highly decorated Marine Corps fighter pilot in both World War II and the Korean War, rising to the level of Colonel. Then, as immortalized in the book and movie “The Right Stuff,” Glenn was chosen as one of the original NASA Mercury Seven astronauts, where he became the first American to orbit the Earth in 1962. Glenn went on to serve four terms as a U.S. Senator from Ohio, and he even returned to space at age 77, the oldest person ever to do so. In between, Glenn ran for president in the 1984 Democratic Party primaries.

What do all of John Glenn’s heroic accomplishments have in common? They were all done as part of the U.S. Government.
