I am sure you would agree that communication is a vital part of emergency response
Yes I would agree. However, what you deliberately appear to be refusing to understand is that getting the aircraft safely on the ground is "more vital" than communication.
To put it another way, do you want a pilot make a long PA about how "things are going to be alright" or would you prefer that pilot
make things turn out alright by landing the aircraft in a safe manner as soon as possible.
Through my own experiences I can guarantee that you might not have time to do both, so
what would you rather your pilot do?
But a plane full of pax switching of an engine mid air not requesting emergency assistance? That's odd for me.
How do you know that they didn't?
DIVOSH!
