Having been in a rollover incident many years ago in a R22, I can vouch for the fact that it is easy to smack your head during such an accident, something that could easily prove fatal and is not unique to robbies.
Of course, though a head trauma like that often proves fatal after the event and not at time of impact.
There seems to be fairly significant damage to the instructor side of the cockpit, while the rest of the aircraft seems to be in fairly good condition, hence the comment.
The Cabri as an example has had it's fair share of accidents in quote/unquote the landing phase and the cockpit remained in good condition. Different architecture and design philosophies but given the choice I know which one I would choose.
From the stats quoted further up, it would seem the ideal training aircraft is a 206, confirms what everyone already knows.
