In 1947, Captain Chuck Yeager became the first human to fly faster than the speed of sound. Piloting the X-1 supersonic plane, he left this goal in the dust of the craft he nicknamed "Glamorous Glennis" after his wife.

Now, more than 70 years later, the U.S. Air Force has given the latest supersonic plane its experimental "X-plane" designation, NASA has revealed. The craft—now called the X-59 QueSST—is designed to shed the deafening sonic booms normally associated with super-fast airplanes.
