There is something unique about what has happened here and I don’t believe we will find out for a while. It’s clear the PIC had very little control once they started the base turn. Something happened. It wasn’t a steep turn. The speed looks good.
It’s almost as if the PIC didn’t have hands on the controls once that turn started, or that was nil control response for whatever reason. Did something impact the windscreen? Did the seat slide back? Obviously serious structural/cable failure is another. Age is young, medical issues would be extremely unlikely.
