1. An ultralight parachute enabling to jump with, from any altitude and still hit the ground with tolerable impact, comprising a number of distinct and separate inflatables joined by flexible thin threads, such inflatables being either spherical or torus-shaped where the central outer hole of the torus is covered by a flat thin shroud bonded, fused or adhesively joined to it, whereas the aggregate buoyancy in the air of such inflatables, when fully inflated with lighter-than-surrounding-air gas through a conduit, from a vessel situated outside the parachute and containing said lighter-than-surrounding-air gas, will exceed the total weight of the parachute and will cause it to rise to a height above the potential jumper or the attachable load, and whereas when said inflatables are drawn towards the ground by the weight of the load or the jumper suddenly added to them, their aggregate total surface projected in the direction of the motion will be such that the aerodynamic countering force engendered by their motion in the air, will equal or surpass the weight of the load or the jumper and decelerate their motion, such parachute also comprising load carrying means including straps and harnesses, such load carrying means attached to said inflatables by lightweight flexible attachment means including threads, ribbons, cords, or fibers.
