> Being on the plane doesn't remove your right to free speech
The First Amendment only prevents the government from penalizing your speech. It doesn't stop a private company (airline) kicking you off an airplane for something you said or did.
The PIC (Pilot In Command, aka Captain) is the final authority for the safe operation of the flight (14 CFR Part 91.3). If the Captain determines that a threat exists, they are empowered to do pretty much anything reasonable to deal with the threat. Turning the plane around and landing is certainly in the realm of "reasonable".
Whether you or somebody else who is clearly not an airline captain feel the original actions constituted a threat is pretty much irrelevant.
Signed, airline captain.
I acknowledge that the airline captain has some responsibility for our security. But part of this responsibility is being a steward for our overall well-being. And in this case, the "security" aspect is so vastly overwhelmed by the damage it did to passengers in other ways, that it was obviously a bad call on the captain's part.
It really does break both ways. Over-reacting to perceived threats has a cost too.
Warning - semi-political (but hopefully non-partisan) political content ahead: This is the same thing the FDA does with drug approvals. They are overwhelmingly biased toward preventing bad drugs that they prevent access to a lot of things that could help. Studies show that the FDA's difference between up-side and down-side risk costs a lot of lives on net. For example, the FDA delayed the approval of beta-blockers (used to prevent second heart attacks) for several years after they were widely available and saving lives in Europe. Analysts estimate that this delay alone cost tens of thousands of American lives.
Sometimes, accepting a risk provides the greatest net benefit.
Doesn't 91.3(a) already give the PIC absolute authority to act regardless of whether there's a threat? Why invoke the FBI?
> Turning the plane around and landing is certainly in the realm of "reasonable".
Agreed. But doing it without the FBI threat would also be in the realm of reasonable. Which, it could be argued, means that making the FBI threat was unreasonable, or at least very close to it.
Beyond a certain point, even a PIC can cry wolf.
If an airline pilot is so bereft of fortitude that they perceive a political wifi network name as a threat, they should be disallowed command of the aircraft. They need therapy. Mental weakness like this should not be tolerated in those responsible for the safe operation of human lives.
It is also their right to sue you for abuse of authority if it is proven that said captain abused their authority. Say if said captain was a zionist and decided to take it out on that person by abusing their authority. Having authority does notmake you blameless, there is still a responsibility attached to that authority.
I don't care what your politics are, that is not a reasonable nor credible threat. If there was a credible threat the conversation would be different, but it is a tacky political statement.
