...The P2 and rearcrew are part of the crew and on SAR should have an equal voice regarding the conduct of mission planning and execution - without CVR we won't know anything about that unfortunately..
The time for talking was before they launched in the first place. Had there been a pragmatic and sensible and open and inclusive discussion/appreciation at that stage they would have turned the bus around and gone home. Given that discussion didn't happen, chances are it probably wouldn't have happened in flight either. Or if it did, would have been about as useful as the discussion wasn't in the Rescue 116 accident.
