The balloon, with capsule attached, will move through the lower level of the atmosphere (the troposphere) where our daytoday weather lives. It will climb higher than the tip of Mount Everest ( miles/ kilometers), drifting even higher than the cruising altitude of mercial airliners ( miles/ kilometers) and into the stratosphere. As he crosses the boundary layer (called the tropopause),e can expect a lot of turbulence. 武漢理工大學(xué)《運(yùn)輸包裝》課程設(shè)計(jì)說明書 21 The supersonic descent could happen as early as Sunda.
