I think a part of the problem, as in the case of the Geraldton West Australian Legacy, is unnecessary manoeuvring at low level when an event occurs such as the canopy opening.
I have been at fault myself when an unexpected event occurred, and with hindsight would have conducted the flight differently, and safer.
The different aspect in the case of say the canopy opening, would be to climb straight ahead and put some vertical manoeuvring space in place.
