I'm not one for speculating what happened, but from accounts and now this
picture (takeoff shot of the Legacy that crashed at SNF)... .It appears that
at least part of the trouble was the canopy wasn't latched...

Ok, so who knows how these things fly, if they fly when it comes unlatched
while in flight or in this case, appears to be unlatched prior to
takeoff.... Darn, I feel for the family, but we all need to learn from mistakes and it
appears that "5 alive" wasn't done in this case prior to takeoff :(.... Sad
and probably avoidable...
