Hi! Here's a quick summary of "Chuck Yeager's" accomplishments to provide evidence to the answer.
Chuck Yeager is an American test pilot who was the first person to break the sound barrier — the point where a speeding object (such as an airplane) passes the speed of sound. Yeager made his history-setting flight on Oct. 14, 1947 in an airplane he dubbed Glamorous Glennis, after his first wife.
