He held the world record for the highest skydive—102,800 feet (31.3 km)—from 1960 until 2012. [1] [2] He participated in the Project Manhigh and Project Excelsior high-altitude balloon flight projects from 1956 to 1960 and was the first man to fully witness the curvature of the Earth.
High-altitude balloons or stratostats are usually uncrewed balloons typically filled with helium or hydrogen and released into the stratosphere, generally attaining between 18 and 37 km (11 and 23 mi; 59,000 and 121,000 ft) above sea level. In 2013, a balloon named BS 13-08 reached a record altitude of 53.7 km (33.4 mi; 176,000 ft). [1]
