The para gliding canopies are very delicate and susceptible to
turbulence due to their lower wing loading. Just a little bit of
turbulence and take the canopy and twist it into a not within a second
or two.
My last parachute had a wing loading of about 1.5 lbs per sq/ft and the
material was what is called zero porosity. And it produced a very rigid
airfoil, for a parachute. I know some people who weighed 200+ lbs and
were jumping 90 sq/ft parachutes. Talk about fast landings.
