A little over 50 years ago, Joe Kittinger jumped from a giant helium balloon at 110 degree below zero temperatures to plummet to Earth at a speed of 714 mph and became the first human to break the sound barrier without the aid of a machine. It was literally a “giant” leap for mankind, as Joe threw himself from 102,800 feet above the Earths surface at the horizon of our planet and space. The U.S. Space program used Joe’s test jump as the building block for their future manned space explorations
In 2003 Forbes Global interviewed Joe about this courageous feat. It’s still a great read. Check it out here.
