Sixty-five years after becoming the first human to fly faster than the speed of sound, retired Air Force Brig. Gen. Chuck Yeager is still making noise. This time the 89-year-old Yeager, who was featured in the movie "The Right Stuff," flew in the back seat Sunday of an F-15 Eagle instead of the experimental rocket plane, Bell X-1, he piloted on the historic flight. The F-15 took off from Nellis Air Force Base near Las Vegas and broke the sound barrier at more than 30,000 feet above California's Mojave Desert where Yeager achieved the feat on Oct. 14, 1947.
