Colonel Joseph William Kittinger II (born July 27, 1928) is a retired officer in the United States Air Force (USAF) and a Command Pilot. His initial operational assignment was in fighter aircraft, then he participated in Project Manhigh and Project Excelsior high-altitude balloon flight projects from 1956 to 1960. He set a world record for the highest skydive: 102,800 feet (31.3 km) on August 16, 1960. He was also the first man to make a solo crossing of the Atlantic Ocean in a gas balloon, and the first man to fully witness the curvature of the Earth.

As a fighter pilot during the Vietnam War, Kittinger shot down a North Vietnamese MiG-21 jet fighter. He was later shot down himself, spending 11 months as a prisoner of war in a North Vietnamese prison.

In 2012, Kittinger participated in the Red Bull Stratos project as capsule communicator at age 84, directing Felix Baumgartner on his 24-mile (39 km) freefall from Earth's stratosphere, which broke Kittinger's own 53-year-old record. Baumgartner's record would be broken two years later by Alan Eustace.
