Chuck Yeager achieved Mach 1 in the experimental X-1 plane on this day in 1947. Today, Felix Baumgartner plans to ascend to at least 120,000 feet in a stratospheric balloon and make a freefall jump rushing toward earth at supersonic speeds before parachuting to the ground. His attempt to survive extreme atmospheric limits holds the potential to provide valuable medical and scientific research data for future pioneers. This jump procedure may someday be repeated in a space exploration or space tourism emergency. So the data collected today could help save lives.
