The great Olivier Vietti has made a modern "kind" replica of Leonardo's parachute. With the help of Eric Viret and Eric Laforge. That's a team ...World's premiere! Sure, with modern 0 porosity cloth and nylon lines, it's easier than what Da Vinci would have had to face in his time, with wool, or such heavy porous equipement. And we know now that no wood is needed to maintain the frame, which Da Vinci didn't figure out. Still, it works ! The direction intended was correct.
