Explore dangerous heights alongside early balloonists who risked their lives to explore the upper atmosphere, in this excerpt from AMERICAN EXPERIENCE: Space Men. In 1862, Englishmen James Glaisher and Henry Coxwell set out on a scientific mission to explore high altitudes. They had no idea they would encounter extreme cold or thinning oxygen levels and nearly lost their lives as they reached over 29,000 feet, higher than any human had gone before. This resource is part of the American Experience collection.
