Not quiet right Fred.

 

VH-ALP has the standard canopy hinged from the front. I am not certa= in 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 tra= ils 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 simi= lar accident.

 

I hope Gerry recovers from the terrible burns he has received.<= /o:p>
