Sail-boat (plate 32A) has the tensile structure to hold wind. Similarly the Hand-glider (plate 32B) traps air in the wing to float. The Wing Paradigm is stretching like a skin or sheet. Among the man-made products based on tensile structure sail-boat, hand-glider, umbrella (plate 32C), tents, etc. belongs to Wing-Paradigm.
