Ben Cowen would be alive and well right now had he been flying a hang glider instead of a paraglider.
Because hang gliders have an airframe, the shape of the airfoil does not suddenly distort in turbulence and initiate a turn in the total absence of the pilot's input.
Furthermore, because paragliders have little pitch control compared to hang gliders, it takes much longer to recover from an out-of-control situation.
You can't crank and bank to get out of trouble. Think about that.
I have said for many years that while hang glider pilots can kill themselves by pilot error, but paragliders suddenly kill their pilots when least expected.
It's a no-brainer - and it explains why paraglider pilots think paragliders are great substitutes for real aircraft.
