Chuck Yeager and the Glamorous Glennis

Air Force Captain Chuck Yeager in 1947 flew a BellX-1 airplane, the Glamorous Glennis, at Mach 1.07 over Muroc Dry Lake Bed in California. He successfully conducted the first faster than sound flying experiment.

Felix Baumgartner in 2012 jumped from a hot-air balloon at a height of 24 miles to freefall to earth. He reached a speed of 843.6 miles per hour (Mach 1.25), becoming the first person to break the sound barrier without a vehicle.
