Lots of discussion on whether the crew received information on the true nature of their dilemma.
I think one of the most difficult decisions can often be,"do we need to evacuate",however...once the decision has been made,it is a " read and do" procedure. I believe this to be the case in most airlines in the World.
The boss didn't "read and do"..
shouldn't this be the crux of the discussion!
Maybe he didn't have quick access to the Evacuation Checklist ...either electronic or paper...
