Having visited this subject along with Aircom delegates at ICAR2022, I was interested to find this video on Youtube yesterday
which tells the story of the poster being paralysed in what were effectively three accidents. First, he had a paraglider canopy problem. Second, he tried to deploy his reserve but landed hard and ended up unconscious for 20 minutes and hung-up in his canopy on an outcrop on a mountainside. [Learning Point: TWO canopies near the incident location!] Third, a helicopter attended the incident, reinflating the reserve canopy and throwing him down the slope causing further injury.
Note my youtube comment about how knowledge and understanding of wake turbulence and canopy re-inflation has been progressing.
