Chuck Yeager breaks the sound barrier -- again

Chuck Yeager was 24 when he became the first human to break the speed of sound. And to celebrate the 65th anniversary of that history-making event, the 89-year-old former test pilot and now retired Air Force brigadier general did it again, flying in the rear seat of an F-15 that broke the sound barrier at 10:24 a.m. on Sunday.

Yeager, whose exploits were chronicled in the book (and film) "The Right Stuff," gained worldwide notoriety when his Bell X-1 -- a 30 foot, 11 inch plane with a 28-foot wingspan -- reached a speed of 700 miles per hour, Mach 1.06, at an altitude of 43,000 feet on October 14, 1947. With his flight, the era of supersonic aviation was born.
