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.
