In memory of one of the world's greatest pilots and one of America's great heroes, General Chuck Yeager, who died today at age 97.
A combat pilot becomes an air "ace" after five confirmed enemy kills. During aerial combat with German planes in World War II, Yeager accomplished that feat in a single day. After the war, in 1947, he entered aviation's pantheon when he became the first test pilot in history to break the speed of sound.
