Imagine you're on approach in poor weather, then you are finding yourself in a smoke filled environment during the most critical phase of flight. Whilst your brain is going "OH S***", and you are trying to fly an approach whilst at the same time donning masks, etc.., in diminishing visibility, the radio call he actually made is probably all the poor guy could get out at that moment.
Let's throw some of those commenting in here in that situation and see what happens then.
At least they can die knowing they had perfect RT for the investigators to analyze.
