How strong is a hang glider? Do they ever break in flight? How about paragliders?
Compared to regular airplanes, hang gliders and paragliders are quite strong. While a single engine Cessna might be strong enough to withstand 6 times the normal flight loads on it, hang gliders and paragliders can usually hold up under eight times the normal load or more. Even so, they do sometimes fail in flight. In most cases, this is a result of the pilot operating the glider outside of the operating limitations recommended by the manufacturer.
