Okay fellows! Just to wind it back in
The facts that we have are:
1) Witnesses saw smoke from #2 engine. So, it is more than reasonable to assume this was a “bad engine”
2) At the crash site, #2 was delivering power and #1 was not and neither was its propeller feathered.
The state of #1 engine/propeller has only a number of possibilities
a) #1 engine failed and did not auto feather
b) #1 engine was shut down incorrectly and did not feather
Whatever the case is, it is highly unlikely that flight could have been sustained for any longer than it was due to the drag from the prop and possibly lower power from #2
I know that a lot of people including myself are hoping that possibility a) will be the outcome for the sake of the crew but in all probability what are the chances.
In any event, assuming the worst possibility and in that short space of time the crew had to react, they did well.
Good luck to them and a speedy recovery to all who were injured
