How high is the sky? On August 16, 1960, Joe Kittinger rode a balloon to the edge of Earth’s atmosphere. Up there, where the temperature is -94 degrees Fahrenheit yet blood would boil, he stepped off the platform and plunged 102,800 feet, twice as high as jetliners flew. His speed: 614 miles per hour, approached the sound barrier.

Earth’s atmosphere extends 6,200 miles above the planet. After that, the atmosphere blends into space. In jumping from over 19 miles above the Earth, Kittinger  reached beyond the sky’s limits. Fifty-two years later, he helped Felix Baumgartner repeat that experience.  Watch Joe Kittinger’s jump [3 minutes].

The theme for this fourth of four “Beyond the Sky’s Limits” posts is, “Travel.” Photographs from my “SkyScapes Gallery” accompany this series. Here are five favorite quotes,
