Twitter allegedly deleting negative tweets about United Airlines incident

Granted, of course. But it does give the captain the authority, I'd claim - you follow the orders, and then later (outside the airplane) might discuss, question, and take legal recourse.

What if you refuse to switch off your electronic device during take-off, pointing out (correctly, most likely) that it's not actually safety relevant? Or you refuse to move your luggage, sitting in a window seat, arguing that it won't hamper anyone's evacuation? Or what if someone is standing up during taxi arguing that most likely there won't be any sudden acceleration, if so only they themselves are likely to be injured, and they'll hold on to something anyways?

Or, to take a case I've thought about a lot, Saudia Flight 163. The plane took off, caught fire, landed, and taxied. Apparently there was some delay before evacuation, and all people on board perished in the fire. Maybe they would've been better off if some pax had initiated the evacuation before the order was given. Does that now justify that we make our own judgement as passengers as to when to evacuate? And talking of evacuation, you are not supposed to bring your cabin luggage with you as it might obstruct others. But hey, I'll be really fast taking it out, and it's really important to me (maybe I'm a doctor, and my stethoscope is in there), and it's really small, so I'll just take my luggage anyway, I'm so special and it's not safety relevant in my judgement. Do you really want to open the door to everyone making their own judgements in these matters?

See, my instinct in all these cases is - no, you follow the instructions of the crew. Part of it is historical, of course - aviation used to be a dangerous business. In the army and on a ship and in an airplane, you follow orders by the commander - because the stakes are so high (death, and not only for yourself, but also for others), and the asymmetry in information is so high.

Now, yes, there are exceptions (in another comment board someone, in true Godwin's law, did bring up the holocaust and slavery when I argued for following the law), see the Radbruch formula, developed by German law professors after WW II stating that you have to follow the law, unless "it is unbearably injust".

So my point in this whole discussion (as a pilot myself with a smidgen of familiarity with the airline business) is: you follow the instructions of the captain (and by extension, crew), except in extreme cases, or suffer the consequences.

Now, you could make the argument that these broad historical circumstances have shifted. Aviation has been a victim of its own success, in a sense - it is so incredibly safe today (thanks to adherence to well thought-out procedures), that people perceive it more like a bus trip than a dangerous journey. And who wants to listen to a bus driver? What expertise does he have? We all know how to drive.

That argument can be made, and maybe it is right. But I'd argue that if we let everyone make their own judgements as to what is safe or legal on board, we jeopardise the very safety that's been achieved. So far, the jurisdiction of captain and crew on a plane or vessel are pretty absolute (remember that they can or could perform marriages, for example), I'd say, and deliberately so.

Is this a case where that authority has been abused? Maybe (though if the deadheading crew didn't reach their destination, planeloads of pax would have been denied a flight). But is it a reason to throw the whole edifice out of the window? I don't think so, yet.

PS: I note in passing that my posts on this issue are my most down voted ever, burning some Karma here, but hey, saying what I think :-)

Maybe twitter has a team of lawyers sending them lists of Ids to remove, citing DMCA or whatever.

Of course the hypothetical team of lawyers couldn't keep up, and the whole idea is ludicrous, but twitter might comply.

Who knows?

The scope creep of these powers increases the risk of abusing that power, and when people are caught in the act of abusing power, it reduces trust. And that loss of trust can risk lives in situations where a very high degree of trust is needed. So I take the position that FAR 91.3 and 91.11 do not make the crew god emperors in all things. I apply those regulations contextually.

And the context of the story of the week, that passenger was not in any way shape or form a safety risk to himself or anyone else, including the crew and therefore FARs simply do not apply at all. This was an airline business decision, it was strictly about money. I'm not going to deny a person who has the capacity to distinguish contexts from peacefully resisting a bullshit business request that relates to the airline's profits. You can't or don't want to distinguish contexts - fine for you.

As for flight 163, is an interesting choice given your position. Basically that airline had not learned the lessons of the 1977 Tenerife accident, which is basically that the absolute authority of the PIC is bullshit. That whole archaic culture of what the captain says goes, he's always right, do not question, just do what you're told, is a dead end concept from a bygone era. Now, we have crew resource management which merges the idea of all crew having a say when it comes to bringing up concerns related to safety, and once they've had their say the PIC is the final authority rather than an absolute authority. There's a difference.

Anyway, when everyone dies in an accident, it's hard to argue after the fact that the PIC was right, and everyone was right to just follow the orders.

Not denying in the least BTW the lessons of Tenerife/CRM (and I brought up the Saudi 163 example precisely because it challenges PIC authority), just arguing that the devolution of authority should go as far as the crew, but not extend to pax.

As for distinguishing contexts, my argument is that an airplane is not the right place to have that discussion. Say I use my mobile phone, arguing that it is not actually safety relevant, and only a business decision by the airline because they want me to use their expensive credit card sat phone. Then when crew asks me to switch it off, I refuse, and when they ask me to disembark, I refuse, as it's a commercial issue, not safety or ops. It seems like a slippery slope.
