Drachen kite balloon, showing its characteristic shape. A kite balloon is a tethered balloon which is shaped to help make it stable in low and moderate winds and to increase its lift. It typically comprises a streamlined envelope with stabilising features and a harness or yoke connecting it to the main tether and a second harness connected to ...
In 1956, Jalbert tested his square parachute for the first time in Boca Raton, Florida. Annotated form of drawing from April 15, 1944 patent for Kite Balloon In 1957, Jalbert invented the ram-air airfoil and began testing and formalizing the design.
US Marine Corps barrage balloon, Parris Island, South Carolina, in May 1942 A barrage balloon is a type of airborne barrage, a large uncrewed tethered balloon used to defend ground targets against aircraft attack, by raising aloft steel cables which pose a severe risk of collision with hostile aircraft, making the attacker's approach difficult and hazardous.

These automatically form a triangular shaped parachute [8] which carries the spider away on updrafts of winds where even the slightest of breezes will disperse the arachnid. [7] [8] The Earth's static electric field may also provide lift in windless conditions. [9] [10] Ballooning behavior may be triggered by favorable electric fields. [11] [12]
