I once merely mentioned the words “Heart Attack” on a plane and was kicked off by the flight attendants. No context, they just heard the words and forced me off.
There are things that trigger them because of laws and regulations like mentioning “bomb” (even if you’re describing something fantastic).
So messing with the gogo flight entertainment is up there with flirting with terrorism charges.
I would never in a thousand years run a sweep on an airplane network. That's massively risky, to the point you might never be allowed on a jet again. Anything to do with aviation I am on my absolute best behaviour.
I was on airplane with large aggressive dog, that was harassing other passengers. I was worried it would ampute my limb mid flight.
I voluntary left before take off, dog stayed!
Hijacked plane is a popular media spectacle with lots of ties to other images and scenes. Millions are ready to discuss it, or listen to the thrilling stories. “This is important for security!” is a shazam in that context. At the same time, much closer and routine dangers directly affecting many people (power plants, refineries, railroads and so on) are kept in check by underpaid workers who can't even make companies fix sensors or replace something until it is rusted through. Effectively, “this is not important for anything”, nor public is interested in TV shows about working pipeline that is not getting blown up. Those who want money and power naturally stick to impressions that work for the crowd they are given.
Propaganda is most successful when people do the required thing on their own, agree that it's absolutely impossible to evade, and even encourage each other. Something in this day and age makes people themselves adore certain forms of propaganda, and even demand to be told specific lies. Among other things, images of stupid social machines crushing someone (“they'll put you on the list”, etc.) seem to weirdly stimulate the crowd.
Even in so-called globalised world there are examples that crack the habituation. In country A, any big gathering of people needs to be formally approved, supplied with hordes of policemen (thankfully, not tanks), fences (thankfully, not barbed wire), entrance searches (thankfully, without stripping). When you ask anyone about that, they promptly respond with “What if terrorists/enemies decide to attack the crowd?” or “What if they start to riot?” (notice that “they”), etc. Even most obvious security theatre acts are automatically accepted with promotion to “psychological stuff that helps to detect those people in the crowd”. In country B, no less “civilised”, the same event is handled by some private company that is mostly worried about portable toilets or electric generators, and people come freely to the venue if they like it (just buy the ticket).
The odds of something wrong happening are roughly the same, but people reason about themselves and those around them very differently. That mental picture of the world shapes the thing that happens, not the alleged expert opinions or calculations.
The fun thing to do on the plane is clone the wifi and add an option to log in with google or meta or apple credentials....
Well now you have a chance to tell your side - were you merely sitting and just uttered the words "heart attack" for no externally apparent reason?
