It is interesting how the report dances around the decision to evacuate or not but avoids reaching a conclusion on that.
It comments on the crew not getting as much info as they could have but holds back on the decision itself.
The transcript is interesting: fire commander reports that fire is pretty big and that he is attempting to control it. It is some time before it is reported under control. It is hard to believe that first transmission from the FC didn't lead to evac. Maybe the crew made the right call, but it must have taken extreme coolness to stay put at that point.
