FILE - In this Saturday, Oct. 26, 2002, file photo, retired Air Force Brig. Gen. Chuck Yeager receives a plaque from the National Defense Industrial Association, recognizing his breaking of the sound barrier and the use of X- 1 loading pit, at Edwards Air Force Base, Calif. Yeager again broke the sound barrier Saturday, for what he said was the last time, more than a half-century after he became the first person to accomplish the feat. Yeager took an F-15 Eagle to just over 30,000 feet.
