The only thing achieved here was to build a wall between myself and theflight attendants....
You are totally right and thats rather worrying. I am Cabin Crew and I have never felt that I could not question a pilot on something that either concerned or worried me, respectfully of course.
Why would Cabin Crew be expected to know how to fly a plane or your procedures in the flight deck? They don't! If you make a mistake when your responsible for our lives as well as the passengers then you should be held to account.
Beggars belief the only way you have to vent is by berating Cabin Crew.
