Virgil Ivan Grissom, widely noted as Gus Grissom (April 3, 1926 – January 27, 1967) was one of the original NASA Project Mercury astronauts and a United States Air Force pilot. He was the second American to fly in space and the first person to fly in space twice. Grissom was killed along with fellow astronauts Ed White and Roger Chaffee during a pre-launch test for the Apollo 1 mission at the Kennedy Space Center. He was a recipient of the Distinguished Flying Cross and, posthumously, the Congressional Space Medal of Honor.
