So, what kind of "few words" would work then with a bunch of panicked retards? Passengers have responsibilities as well as the rights they are so fond of quoting. This is not touchy-feely customer service stuff; it's beyond stupid to jump up out of your seat on a take off roll, panic other pax and go banging on the cockpit door - we're not exactly talking about using your cellphone despite being told to switch it off here. You have to ask yourself, if If you’re a seated pax on that flight and some guy jumps up screaming fire, we’re all going to die, and makes a run for the cockpit door, are you going to join him? Do you see queues of people lining up to go with the odd person who wigs out and tries to open an exit door? Are we going to end up reading a pre-tax takeoff list to pax for an hour over the intercom to cover the million potential eventualities that may concern them in their ignorance? Yes, we're sure the doors are locked, yes, we're sure the aircraft has been checked by a qualified engineer, we have enough fuel, yada yada. Do you think people like that would listen to a cc briefing on the intercom in the first place, or pay attention to the safety drill even? And if there is something genuine spotted by concerned pax, it's not best communicated by banging on the cockpit door, that's the kind of thing that could get you shot in the States as someone else pointed out, even if you're not on a takeoff roll.
What happened to these people after the event, have they been charged or will they be blacklisted?
