The passengers react in whatever manner they consider appropriate because they consider they know better than the crew?
Can someone please list the occasions when passengers knew better how to deal with the problem than the crew paid to do so?
What if the pax is an aircraft engineer on vacation?
Cabin crew are not paid to diagnose aircraft defects, but are expected to assume the responsiblity of doing so?
Then there are stories of cabin crew unable to make the pilots understand the nature of the problem. e.g. The cabin crew of an old 747 report that a probe (not sure of the exact words they used) on the wingtip is adrift/dangling down. The pilots somehow thought that the cabin crew meant one of the static probes (wicks). They actually mean the rather heavy, 6 foot HF antenna. I heard it fell off, but luckily no one was underneath at the time.
