You make a fair point in the last paragraph Rainboe and I am sure it will happen.
Flying aeroplanes does not make you a good leader. I am reasonably sure that leadership is not a prime measure, when promoting a first officer to command. It would never have been in the job role. Hiding behind the law of the sky, does not promote good leadership skills.
In most other jobs, leaders are selected because of their leadership skills. This is true for cabin crew. is it the same for flight crew?
A few years ago I attended a presentation by BA for wannabee pilots.
The question was "Who wants to be a pilot with BA?"
Lots of hands went up. The reply was :-
" Well we are not looking for pilots but are looking for those who can manage a multi £M piece of equipment, CC, passengers etc. We will then teach them to fly"
That made a few of them think!
