The BLAST high-altitude balloon just before launch on June 12, 2005. 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.
The JP Aerospace Twin Balloons Airship is an unmanned airship comprising two balloon envelopes side by side, with twin electric-powered propellers mounted midway along the connecting boom. On October 22, 2011 it is claimed to have flown to 95,085 feet (ca. 28,982 m), nearly 4 miles higher than any airship before. [10] [11]
Urban Sky Remote Sensing balloons operate in the stratosphere at an altitude of about 20km (about 65,000 feet), and are roughly the size of a car at launch with a payload attached underneath. [18] [19] The balloons grow in volume as they ascend and are roughly 11 times larger in the stratosphere than when they are near the ground. [20]

In 1935 and 1936, to reduce weight and thus enabling a balloon to reach higher altitudes, plastic balloon construction began independently by Max Cosyns in Belgium, Erich Regener in Germany, and Thomas H. Johnson and Jean Piccard, then at the Franklin Institute's Bartol Research Foundation in Swarthmore, Pennsylvania.
