    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]

    Explorer II was a crewed U.S. high-altitude balloon that was launched on November 11, 1935, and reached a record altitude of 22,066 m (72,395 ft). Launched at 8:00 am from the Stratobowl in South Dakota, the helium balloon carried a two-man crew consisting of U. S. Army Air Corps Captains Albert W. Stevens and Orvil A. Anderson inside a sealed, spherical cabin.

    en.wikipedia.org/wiki/High-altitude_balloon

    Geostationary balloon satellites (GBS) are proposed high-altitude balloons that would float in the mid-stratosphere (60,000 to 70,000 feet (18 to 21 km) above sea level) at a fixed point over the Earth's surface and thereby act as an atmospheric satellite. At those altitudes, air density is around 1/15 to 1/20 [37] of what it is at sea level ...
