The primary advantage of a kytoon is that it remains in a reasonably stable position above the tether point, irrespective of the strength of wind, whereas ordinary balloons and kites are less stable.
In 1919, a handbook was published giving extensive details to support the kite balloon crafts being used in the military.
"This was the first real kite balloon flying like a kite with a fairly constant angle and direction relative to the wind and remained practically unchanged until the beginning of the war in 1914-1918.
In low or gusty winds a kite can nose-dive, losing a large amount of height even if it recovers.
Because a kytoon is buoyant it does not nose-dive and remains in position even in relatively still air.
