You guys are missing the point. I'm sure Mr. O'Brien has no disrespect for an individual's experience on specific types, & basically has to blag his way "professionally" through a flight on a heavy jet, to satisfy the director as well as the audience. Would it be exciting television entertainment if he sat on the jump seat & said "I don't know anything about this, so I'm just going to watch."
I know I would find it difficult to provide a running commentary which would appeal to couch potatoes when I am flying.
THIS IS NOT A DOCUMENTARY PROGRAMME. IT IS LIGHT ENTERTAINMENT FOR NON-AVIATORS.
For crying out loud guys, day to day operations are just too boring to appeal to the man on the street as exciting. Let the public be entertained.
