You're probably right, johns7022, but until pilots are all replaced by drones, those aircrews that consist of more than one person in the cockpit (or in the plane for that matter) are going to be in teams, and the evidence suggests that that those teams who were not trained to communicate and coordinate their activities well have in the past flown into other planes, or into mountains, or run out of fuel, or not noticed there was too much ice on the wing, or forgotten to depressurise the doors after successfully landing a plane on fire, or not taken over command of the plane fast enough when the captain had a heart attack etc. etc. On the other hand other aircrews have saved hundreds of lives not just through good technical flying, but through communicating and working well together in a crisis. Do you really think that stuff comes naturally to everyone? I'd agree that some people can't be taught anything, and they probably shouldn't be pilots, but do you really think pilots who have to work in aircrews do not benefit from CRM training? I'm intrigued.
