Dr. Hans Guido Mutke (March 25, 1921 in Neiße - April 8, 2004 in Munich, Germany) was a fighter pilot for the German Luftwaffe during World War II. He claimed to be the first person to break the sound barrier and to achieve supersonic flight, although this claim is disputed.

After the war he worked as an airline pilot and as a doctor for aviation medicine. He died on April 8th 2004 during a heart valve operation.

Germany's Me262 was the world's very first operational turbojet-powered aircraft, allowing it to outmaneuver and out-sprint Allied fighter escorts. It actually began development in April 1939, and the eventual result was a fighter that marked a significant leap forward in aircraft design. However, the two Jumo 004 jet engines on each fighter were also a weak point, as turbojets were still in their infancy. The average jet engine's operational lifespan on an Me262 was a mere 12 hours!
