K, I think "the last thing" any "modern two man crew" does, in a crisis, regardless of "training" is get on the radio.
When it all goes to hell, they try to troubleshoot first.
You DO NOT "communicate" to "the outside world" until you know what you want, what you need, and who from.
You do not transmit until you know what you are going to say.
If the crisis continues, they become "discombobulated", and they never "communicate".
The evidence of AF447, QZ8501 and MS804 proves that.
