I am old and allowed to be miserable.
It's the narcissistic, selfie society we have become that annoys me. I can see the point of camera(s) to take pictures of the view but these were all mounted so that the cameras were filming the cockpit. If they were for the purposes of an instructional video then fair enough I'm out of order.
I'm sure I do stuff that would bore the pants off of everyone else but I don't film it.
