World view also offer traditional, uncontrolled high-altitude balloon flights (which just drift freely, without any control of direction of travel, in the winds of the high atmosphere) with their so-called Z-Class flight vehicle. The Z-Class vehicle has much larger payload capability and higher operating altitude compared to the Stratollite.
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 Hawk30 flying-wing is a development of the NASA Pathfinder and NASA Helios high-altitude, long-endurance unmanned aircraft built by AeroVironment for NASA. [2] Resembling the 1999 Helios, the tailless aircraft is a 256 ft (78 m) span flying wing with 10 electric-driven propellers. Orbiting at 65,000 ft (20,000 m), it is solar-powered by day ...

In aeronautics, atmospheric station-keeping is keeping an aircraft in a specified region in relation to the earth. For an aerostat such as a balloon this could be achieved either by propelling the craft laterally against the wind or by utilizing altitude control mechanisms causing the balloon to go up and down in the sky where it can access different wind layers where the wind is blowing in ...
