Not quiet right Fred.
VH-ALP has the standard canopy hinged from the front. I am not certain if it was or wasn't a training flight, but hear there was only one on board.
The aircraft can be flown safely with the canopy unlatched as it trails in the slip stream. It would however be very distracting and noisy.
If in fact it was an unlocked canopy that caused this accident it is not the first Legacy to be lost in that manner. Oshkosh about 3 years ago saw a similar accident.
I hope Gerry recovers from the terrible burns he has received.
