Civil Disobedience aboard a flight, is not "merely frowned upon." There is neither freedom nor license to "act out" or "act up" or "do your thing" or other "disruptive behavior" until ordered to behave.
One look of "Because I say so" from a crewmember, shall suffice as a threshhold that all passengers should wisely obey.
The federal Zero Tolerance policy for unruly or dangerous airline passenger behavior, is still in effect.
Failure to obey an order from an airline employee aboard a flight, and/or interferring with crewmember activity, can result in arrest. Children, parents, guardians.
My first airline flight was 73 years ago (I was a kid). People behaved. We were lucky to be alive and free after World War II. Aircraft were not "buses." We respected the people, and the miracle, of flight . . . and God's grace.
Several pilots still used the boots that they wore during the war. Some pilots, co-pilots, carried a firearm in their briefcase or satchel or B-4. There was a curtain, no door, between the cockpit and cabin areas. The airline stewardesses were mostly nurses, and some with college degrees. They were smart people, worthy of passengers behaving themselves - which most did, because they were raised well.
I should add, that people did not hate one another - that is the message preached, sold, and taught by modern day "progressives."
When flying, the miracle of air passing over the wing, flowing faster than air under the wing, was interesting, but still, there was, and is, God's grace.
Be thankful.
I always remember that when flying and I pray for God's grace to keep the plane up and safely to its destination.
